Final Post on Politics & Religion

I am done talking about politics & religion both online and in real life. For one thing, people can't have a fucking civil discussion on these topics, especially if you have a difference of opinions. Even if your opinion is based on ignorance, instead of other people correcting you on any misinformation, they just resort to childish and they tend to automatically disregard everything you say in the future. I am of course, speaking from personal experience.

This may sound like a stupid question, but what is it about religion and politics that piss people off so much?
