Being a non-native speaker doesn't help, for sure, but one can learn. Point in fact: I'm french :) And as a non-native speaker, I find it great that English has well-known gender neutral pronouns, so I'm more than happy to use them. I wish French had one so commonly accepted as "they" and "it".
Also I don't know if you refer to my post as aggressive, but if so I'd appreciate if you could tell me why. I haven't called anyone names, and I think I responded respectfully to the OP.
