The internet does make people say things they wouldn’t say in person. Not everyone and I believe liberals get nasty more than conservatives. I’ve stopped talking to lots of former friends and relatives because they said things to me on the internet they would never have said to my face.
Scroll through the comments of pretty much any YouTube video and you will find a plethora of not only vile commentary but a lot of atheistic tripe and Jew conspiracy claptrap.
