I'll gladly take the opportunity to avoid directly supporting a racist/bigot, or anyone who seeks to silence/oppress/murder entire groups of people for simply existing. I don't care if they're selling me an application, or a laptop, or a car, or a cheeseburger. The internet, and the world, are a lot more interesting and exciting when you get a lot of different people from different backgrounds participating. Genius and innovation can come from anywhere. Morally and practically I think we're better off being inclusive.

I may not know who on the internet is a dog, but I'm glad those dogs are out there and if somebody is a proud supporter of puppy genocide I'd rather not encourage/enable their misguided crusade so that does factor into my choices.

It isn't something that can always be avoided, or even something that needs to be avoided entirely 100% of the time (I still read Lovecraft for example) but I do think it's worth some consideration.
