I don’t think that speech which harms minoritised groups should be protected. I don’t think that giving another platform to someone who has engaged in hate speech regarding a minoritised group is necessary or that it will add to any ongoing debate. I don’t think that providing a platform to someone who has engaged in hate speech will in any way help them realise that they are harming a group of people, nor will it educate those who are on the fence regarding an issue. In my opinion all it does is reaffirm their existing position, it does not give them an opportunity to learn about how they have harmed others, nor an opportunity for others who do not understand that harm, to understand it better. I am really not a fan of people (who usually have multiple other platforms) being given another platform to other or dehumanise groups of vulnerable people.
Before I go any further I want to state I am not a trans person, I am cis-gendered. I do my best to be a good ally to the trans community, but I will (and do) fuck up from time to time. I will do my best to learn from my mistakes.
