If Asim sounded as homophobic so did Vishal Paras and Sana who were mocking Gupta and imitating his mannerisms.
Only difference was Asim and Gupta's interaction was a direct one while Vishal and Chabra are exhibiting homophobic behind Gupta's back.
None of them were right yet only Asim gets called out because he is a bigger name than Vishal and Chabra right now.
