I do so enjoy people getting het up about grammar.
This video covers a topic that I find interesting and have never thought about quite in this way. Many languages have gender-neutral third-person pronouns, but English is often thought not to be one of them. That thinking is wrong, and Colonel Sanders' grumpy brother here is about to school you.
If you want more, you can find his grumpy language blog here. A choice quote from a recent post: "I’ll take pie rather than cake, gin rather than vodka in my martini, and silence rather than noise about pet peeves." (I'm definitely with him on the gin, and I suppose we did serve pie in lieu of cake at my wedding.)
Get assimilated.
