Welcome to the free West, where people are arrested because someone feels 'offended.' Millions of people died in two world wars to protect us from this sort of idiocy. We're sleepwalking into totalitarianism where what you might think and what you might say are more important than what you actually do.
Note the third photo of Fred celebrating with his top off. The face he is puling is an arrestable offence if you are white and pull the same face.
