This is a great example of mistaking a nuanced social issue with one that has a binary answer. In many social situations saying "guys" is not gender specific... but that does not mean that it is "perfectly" fine to use in all cases. Some people may find it offensive or exclusionary in some cases and it doesn't hurt to be respectful of that. We should of course be on the lookout for those who would try to chill free expression via enforcing some sort of Orwellian newspeak by making baseless accusations of being offended/excluded/discriminated against... but those people are rare, pretty easy to spot, and outnumbered by good people who have legitimate complaints. And BTW if you want to have credibility when calling out the former, it might be a good idea to be respectful and earn gravitas in the eyes of the latter.
