Trolls are far less hostile compared to the mid 2000s, notably GNAA / 4Chan. Only a small minority are a real malevolent nature, using tactics such as hacking and SWATTING. Otherwise, most trolls are soft. Look at Chan culture. If someone threatened suicide or fucked with a Raid they would likely have their lives ruined. Now, raids are mostly banned and half the posters try to talk the suicidal guy out of it.
Only a weak minded lot is even negatively effected by the common troll. Who cares about some 15 year old spamming racist memes they got off DailyStormer or /pol/? Trolls are a good thing. They are a central asset to the cultivation of memes and internet culture. The average joe is the one to destroy most sites and communities. I prefer lulzy trolls over millions of mindless chads and stacies in the comments sections of a youtube video. About 25% of trolls are genuinely truly evil. They're the ones who make fun of cancer victims or other innocents.
We have seen how troll culture has occasionally broke through to the mainstream. Take for instance Anonymous back in 2003~2008. Or the hijacking of Pepe and triggering the ADL / MSM. It'll be fun to watch an alt-right rise to be equal to feminism and SJWism in power, clashing hard and going down in the history books.
