Open minded has always meant to me (and always will mean to me), being receptive to new ideas. Open means things (ideas) can flow in or out. So open minded is about the flow of ideas in and out of the mind. As in, out with the old ideas and in with new ones.
However, an open mind does no good if there is no evaluative process to go with it. Newness is not inherent grounds for acceptance. Validity is. If something is valid, it gets accepted. If not--rejected. Period.
Also, if someone does something without it being a choice, then that is not ethical value.
That is legal compliance--no more, no less. Laws are necessary, to my mind, when disorder would result from not having the law...but I do not think it is the government's place to legislate what goes into my body, ESPECIALLY when some of us have dietary requirements that would not be satisfied on a vegetarian diet without living on pills, or being in constant pain, which WOULD be the result if I tried to alter the balance of my diet.
Legislation, however, is much more appropriate when it comes to the conditions on the so-called "farms" where animals are raised. If farmers will not provide adequate living conditions, and if slaughterhouses will not carry out the slaughter in the quickest, most painless manner they can, then this is a place for the government to step in and enforce compliance.
Supply and demand, however, should be settled by the free market. Demand drops enough--people in the meat business take the financial hit and get out of the business and available supply will come into line with the new, reduced demand. And that is a choice made by the people, not by the government. I would not mind at all if demand dropped and
fewer of us were eating meat, and restaurants served more reasonable portions by their own choice (Example: I went to Wendy's today and got a burger, but I ONLY order the Junior burger because I can actually eat it and I know I will not leave leftovers--I can be sure in that case I don't have a part in a creature dying that does not go directly to my nourishment), and people were similarly more responsible in their buying habits so that we only have to kill what we must, and not to pile a whole bunch of extra on someone's plate that's just going to get thrown out.
I think this would be a good thing. But bringing the government into it I think is a tremendous overstep. If people want to protest and make their case, go ahead. If they want to invoke force, be it by law or by direct violence against those with whom they disagree, then I have a problem.
