Because people aren't familiar with them and need to be made aware of what they really are. Too many people don't see the damage these trolls cause because they get blocked and only see the complaints and I'm realizing that defederation has worked in their favor. If anyone actually read the shit they post they would realize they are conservatives trying to make the left look like psychopaths. They appropriate LGBT and other social justice causes in order to attempt to infiltrate the left and rot it from within. Also, they use liberal as a slur.
