I would need to see some proof. Exactly because of the examples I listed above.
Here's the URL for an illuminative history of the attempts to bring Gays into Star Trek up to 1991 (the original link is down, but the archvie has it):

There's another good link or two at the bottom of the piece.
Note that
In an January 2000 interview for fandom.com, ex-Star Trek: The Next Generation and Star Trek: Deep Space Nine executive producer/story editor/writer Ronald Moore responded to the question of why there are no gay characters in Star Trek: "This is one of those uncomfortable questions I hated getting when I was working on the show, because there is no good answer for it. There is no answer for it other than people in charge don't want gay characters in Star Trek, period. This stuff about, How would you know? Maybe there are lots of people walking through those corridors that are actually gay. What would you have us do? Show them holding hands? That would be ridiculous. Our regulars don't hold hands, which its own kind of a sad commentary on the state of human relations, that they can't even hold hands. Just think about what it would say to have a gay Starfleet captain. It would mean something in Star Trek. It would mean something in science fiction. It would mean something in television. Why isn't Star Trek leading the way anymore, in the social, political front? Gene always said, whether this is true or not, that he saw Star Trek as a way to explore social issues, without the networks catching on. Because it was all couched in space aliens, and ray guns, and space opera type stuff, it gave him a chance to explore social issues, without the networks catching on."
Now "people in charge" could be any number of people, couldn't it. He doesn't specifically say Rick Berman.
But you know what? I've talked with a lot of people on the shows. Writers, directors, actors, interns, licensing people, licensees... Every single one of them who would talk about the situation laid it on Berman (although a few have said that Braga wasn't much better).
There is a lot more that I can't talk about publicly, including how things were handled when we brought gay characters into Marvel Comics TREK, and when we did ROGUE for Pocket. Let's just say that I have zero reason to doubt what everybody told me.
More specific proof?
In a 1995 interview for The Advocate with Patrick Stewart, the interviewer remarked that in "The Outcast," the characters all looked like lesbians. Stewart responded "
Now, that would really upset the producers! But you're right, it was singularly absent from the show. Given what growth and advancement have been made in the past 20years - even in the most rigid male bastions like the military—one would have thought that
Star Trekwould be the ideal environment for projecting oneself 400 years forward and saying, "All right, this has happened in 20 years; what might we have achieved in 400 years?""
[Note: so the producers would be upset over characters looking like lesbians?]
In an August 2001 story, TV Guide writer Michael Logan confronted Rick Berman with the rumor that Enterprisewould feature a gay character (specifically Reed). Berman said "That's totally untrue. Well I shouldn't say totally untrue. It has not been discussed. One of these characters may turn out to be gay.
We've just decided not to make an issue of it for the time being."
[Note: so being gay is "an issue" and "the time being" is "NEVER, from 1989-2005 in 622 episodes""?]
In August 2002, Kate Mulgrew gave an interview in which she said, "one would think that Hollywood would be more open-minded at this point, since essentially the whole town is run by the gay community. It makes very little sense if you think about it. No, Star Trek is very strangely by the book in this regard.
Rick Berman, who is a very sagacious man, has been very firm about certain things. I've approached him many, many times over the years about getting a gay character on the show--one whom we could really love, not just a guest star. Y'know, we had blacks, Asians, we even had a handicapped character--and so I thought, this is now beginning to look a bit absurd.
And he said, "In due time." And so, I'm suspecting that on Enterprise they will do something to this effect. I couldn't get it done on mine. And I am sorry for that."

[Note: again, "due time" means "NEVER, from 1989-2005 in 622 episodes""?]
In December 2002, USA Today quoted Rick Berman justifying the continued absence of gay characters. Refering to even the possibility of identifiable gay background characters shown, such as a couple holding hands, Berman said:"That was really the wishful thinking of some people who were constantly at us.
But we don't see heterosexual couples holding hands on the show, so it would be somewhat dishonest of us to see two gay men or lesbians holding hands."

[Note: No, we just see straight people having sex or kissing in almost every episode.]
In an April 2003 interview with Trekweb, Berman stated,
"Stigma' was supposed to be our gay episode, but we sort of copped out."
[Note: so an episode about Vulcan AIDs was Berman's idea of "gay"?]
That's the stuff I can find in 30 minutes of looking online, most of which doesn't take into account countless post-series interviews with actors and production personnel that have been more *ahem* forthright in their criticisms.
