"Fear of hostility"

Going on the basis of the thread title and not so much about the OPs comments.

I have it easy I suppose.

If anyone hurts Lesley, they have to deal with Leslie. I suppose he's like a boyfriend to me in that way.
And Leslie is not the sort you want to make angry.

Sometimes having a spare personality is not all bad.

All the things anyone has ever said about bullying pretty much apply here. Don't give an inch, stand up to anyone that tries to hurt you through word or action. Because if you don't they likely want stop.
