As we all know, every single one of the "legitimate" platforms have been used to plan bad things, too. These kind've articles are simply just ways of smearing one side or another. Well, actually, it's only ever one side that is targeted vociferously. Pretending that a few bad apples that exist everywhere somehow means that entire platforms need to be erased. Life doesn't work like that. People don't work like that either.
The people that write these articles will probably be saying in 10 years that you're an extremist if you eat more than 1 meal a week that contains meat. These people have an agenda that they need to propagate.
