My argument doesn't say they should have been "left alone" though. I'm just saying everyone should have a voice and a right to believe what they believe.
Basically, I believe in the old-school left: The ACLU defending the KKK's right to have rallies, "I may not agree with what you say but I will defend to the death" etc. As far as I can see, having the election and the debate in the public sphere about whether gay marriage should be allowed is a good thing. I just don't think it's a good thing once it goes into the territory of saying, you're not allowed to say that, because we're smart enough to know that you're wrong. If you say the wrong thing, I'll try to take your job. If you contribute to the wrong side of the issue, I'll try to take your job.
I mean, I do get what you're saying -- if someone used to support slavery, and we're using that as an argument for why now after the war they shouldn't run a newspaper (or why I shouldn't buy that newspaper), is that okay? If you put it that way to me, it sounds fine, so on that count maybe I agree with you. How about this, do you think the KKK should be allowed to hold rallies, if racism is what they believe?
