The problem with any people group that reacts like this is they use their power to manipulate and control others (society, business, the government etc.)
It is eroding our freedom of speech, as this nation becomes more and more bullied by groups that decide to "blackmail" society with their threats....
It's wrong.
You think the constitutional rights to free speech should be reserved only for multi million dollar corporations that own and control media outlets? The rights of citizens to organize and speak as a community is in some way damaging to America?
Trump is the bully here, and SNL is the enabler. It isn't even a question of him making more insulting and negative comments about Hispanics. SNL agreeing to let him use there venue and stage implies a kind of endorsement. The fact that in all the decades they have been on TV they have never had a Hispanic in their line up of comedians is disturbing and worthy of a boycott in and of itself.
If anyone that ever said anything controversial or insulting to ANYONE (no preferential treatment here, right?) was banned or prohibited from speaking publically, endorsing etc. there would be no guests appearances or endorsements.
The media would like you to think Trump is the bully. It's just another people group trying to get everyone to jump through hoops for their entertainment.
For the record, don't worry about the Hispanics. They will be the dominant race here in the US very soon. I wouldn't have too much pity for them (even if you are one....)
