I wouldn't bother personally. As I said I'm happy to draw a line under it. But claiming its about ideology is a lie I do think you liking his posts about it being about about ideology rather than personal attacks is a bit wrong though
I have him on ignore so he is posting on a thread I put on GC . I don't want any interaction with him but it's clear he is just trying to get attention. Not sure what more I can do to be honest .
