There is quite literally a place in the top of a post to control font, including bold, italic, etc.
As to the above rant, I think you are wrongly connecting FACT with COMMONLY HELD BELIEF. All of these discussions are based on what people believe, and I have yet to see anyone claim any of your rant as a FACT, let alone the idea that EVERYONE believes it. That's ridiculous and shows you don't actually read the discussions, just get offended when the crowd in general doesn't agree with you.
