You can question these things all you want; there will be those who agree with you, and those who don't. You will get those who feel as strongly about their opinions as you do yours. That's the nature of it. It's not always easy, especially if your opinion is in the minority (although on Joe, I think it's not so lopsided as say, extending Buxton, on this site). Just becuase someone has something to say opposite you, they aren't telling you you can't question it, they are rebutting your statements because they feel differently.
