Lacking any specific examples, I am not sure just what "more PC" means. My personal sense of it is that firearms forums may be changing somewhat, but if I'm seeing what I think I am, it's a Good Thing.
I can't prove it, and it may not be true everywhere, but I have the impression that people who shoot and are pro-RKBA generally may be becoming more "diverse". For example, the
Pink Pistols group would have been impossible when I was young, and I've seen several posters on another board I read openly identify themselves as non-Christian or even atheist when a religious subject came up.
Now, I express no opinion whatever on sexual preference, religious belief or any other non-firearms-related Pressing Questions of the Day. I do, however, agree with our respected host that RKBA is a basic human right, and would like to see people of any and every other opinion come around to that point of view. Of course, that means that arguments on non-RKBA topics become more likely, and I would prefer to see those avoided when possible.
If, as I suspect, we are becoming "more PC" because a more "diverse" group of people are owning firearms, shooting, carrying, becoming more RKBA-aware, etc., and we need to be more careful about our language because of that, then I am all for it. Make no mistake, I'm all for freedom of speech, and all the rest of the Bill of Rights in addition to the 2nd, but if I need to tread a bit more lightly on some topics in some venues so as to advance the cause of the 2nd, I am happy to do that.
Of course, I could be entirely wrong about things being more (or less) PC, and the above is all MHO in any case.
regards,
GR
