The 22nd Century always felt more to me like "The 24th Century Meets the Bush Era" if that makes any sense. Archer and Trip remind me of Bush. Trip looks like Bush and Archer seems like Bush as Captain of a Starship. W could also give the Gazelle Speech.
I stop watching ENT at the middle of second season, but main reason was not ENT, rather necessity of change my life style fundamentally. I did not miss the ENT. I found same as you, Trinneer's physical similarity with his Southern drawl to Bush Jr. very irritating. I remember to tell my Trekkie people " Do they really think, that this guy makes us sympathetic towards Bush Jr. ?" The Suliban/Taliban thing made me angry too. (Especially, when you know who Osama bin Laden was and who trained him to what he was doing.)
For a couple of years, as I was very disappointed from global madness, politicians, NGO's, philosophers etc., I began to read/watch intensively about Age of Enlightenment, wanted to learn more how we could get out of the darkness once. Then ENT was there. I though maybe I can find some answers, how show business/art find some solutions.
Now I have a healthy distance to all my resent feelings. They showed us torturing, looting Archer, who was not proud about it and did not understand himself as a patriot and did not lie us without guilt. Rather he broke down and did everything to establish peace at the quadrant. They showed us hating, revenge looking Trip who could find his peace even with Degra. They showed us brutal Suliban Cabal, also intervened innocent Suliban civilians. They showed us what xenophobia, bigotry, prejudice, etc. mean. They showed us fall of societies, like Vulcan, Klingon, Xindi etc. Whatsoever they showed us, at the end we had a reason to have hope. (TATV is never happened). That's why I become an ENT fan.
I think, if someone would come from TOS/TNG/DS9/VOY era, his/hers professional career would be meaningless with high probability. Think about what would be significance of your career at the Age of Enlightenment (ca. 1700). Even mastering of daily life would be very demanding. It can be frustrating. Nevertheless, if the visitor intelligent enough, he/she could have a great respect what kind of odds their ancestors fight against and maybe help the people to avoid some mistakes, if he/she gain their trust.
