I just had a look myself, out of curiosity. I think you may be worrying too much. I only saw one with the word "gay" in the title... and a rather short minikilt being worn by a rather attractive lady who was stark nekkid except for the kilt skirt. Not something that American eBay could get away with... but I digress. There are French members of this board, one of whom is a kiltmaker, herself. So it seems to me that you shouldn't have any problems; especially considering the history between France and Scotland.
