I get your sentiment and I agree we should face our fears but calling the person a loser is too much. We all have fears and it isn’t right to invalidate them. I don’t think we should find work arounds like AI and just stutter proudly but I understand where OP is coming from. I’m waiting on a call right now and I’m stressed just thinking about it but I’ll make that call like a man and if I stutter badly or not, I’ll go through with it. tl;dr: don’t call people losers and encourage them to face their fears in a positive way
