True. But the even bigger problem is social media. Used to in cities not named Los Angeles and New York City, these type of people found themselves outnumbered and more often than not were afraid to speak out in fear of appearing... well, stupid.
Social media gives these low IQ folk a meeting place. You get 5,000 in a group... suddenly that person feels they have at least 4,999 people that will have their back. Not to mention they can remain anonymous. Throw in the fact that places like Facebook, twitter, etc. promote the lefts ideology and censor those who oppose it... All of this brings them out of the wood work.
