Many discussion threads here seem to be losing sight of the fact that these are internet forums. 99% of the time one doesn't have a clue what gender, race, species etc one's interlocutor is.

There is a perfectly good third person pronoun for this situation. Some might decry it as a neologism, but I suggest it has been around long enough and has firmly entered the language:

"OP".

The worry is though, that under SE's new CoC, this would be found a violation of "no twisting language to work around the gender pronouns" rule.
