The (management or computer) algorithm is likely designed to cut down on pornography and/or "offensive content"; the correlation of the terms bi, lesbian, or gay as metadata to explicit images is likely to be large on a visual platform. If anything is offensive, it's the quickness to jump to "I'm offended by logical explanations and I refuse to come up with practical solutions." Which is to say, I believe that the claim was infantile and deliberatively obtuse. Obviously it wasn't meant as a slight against sexual identity and if you want things to be better, get to work and stop complaining (which is unlikely to happen because complaining is easy and fixing things is hard).

Sometimes a cute riposte or simple response is all that's needed to defuse absurdity. Debating with someone plainly calling everyone racist and sexist isn't likely to bear fruit.

I wish we could get to a state in which the professionally offended would stop wasting others' time and encouraging this doublespeak-nonsense game -- there's only so many minutes in the day and we both wasted daylight on this.
