Also, I was expressing an opinion. I think it has been accepted that we are free to have opinions on the Mudcat, right?

It certainly is an opinion. But it is an opinion about what's in the hearts and minds of others. You have a right to such an opinion, but that sort of thing isn't very conducive to friendly discourse. In fact, I would suggest that it is downright alienating. But if you want to alienate people, that certainly is your decision to make. I note, however, that you do protest when liberals do that sort of thing to you and your fellow conservatives.
