I like Robert. But I think he will lose courage and run away from this. I honestly don't think he could cope with a full-on TRA onslaught.
I think its been on his mind for a while, and he - this might be my imagination - DID backtrack once.
However, I saw him tweet to someone gender critical about 6 weeks ago, saying how much he admired them and he felt he personally should stand up and say more.
I think he's aware of the consequences.
