It brought about unity.

He came under particular attack for a controversial scene entitled festivity featuring drag queens sitting around a table.
Earlier this month, seven people stood trial on charges of making death threats and cyberbullying against Jolly.
Jolly and Herrero were speaking at Series Mania in Lille, which ends Thursday.
