Not really. Internet has distorted the reality. I have talked with lots of them in person and online outside of social network that are all day talking about politics and nothing to do what memes make it seem. Also if you look at right wing memes you will find they are accusing left wing people to be pedos(but same applies). In resume, memes like that don't represent reality, its just a "cultural war" that is used to throw shit against the "other side".
