I don't even like Gottheimer, but literally calm down. He was invited to this event and is actively participating. I have no clue what race/ethnicity you are, but people actually like sharing their culture and traditions with people who don't share the same background. The idea that minority groups will somehow crumble because a white person wore their traditional outfit or ate their food without talking about it's cultural significance is so damn offensive. We can articulate on our own what we find offensive and don't need white people on social media getting angry on our behalf.
