In real life, if you publicly proclaim controversial beliefs, people will probably publicly confront or question you about them. Most of them will not push a debate further if you say "I don't want to talk about this topic" or something similar. But if you say "We seem to disagree about some basic facts", it seems to imply you think they are making basic/obvious mistakes, but you aren't going even going to deign to explain those mistakes to them. In short, it could come off as condescending or rude, and it could easily be averted by being a bit more polite.
