Trump tweeted out his opinion on the "squad" based on their statements, actions and politics. Were they bigoted? Is what the Squad presents bigoted?
Most politics are bigoted, so political statements and opinions usually contain bigotry.
Stating someone is a racist or sexist usually contains bigotry using this definition...."having or revealing an obstinate belief in the superiority of one's own opinions and a prejudiced intolerance of the opinions of others."
Are Trump's tweets racial or sexually bigoted? NO, its all political.
