You should be happy "nerd culture" is being mainstreamed in the first place, so that the things you love are shared with more people. Your main argument over being an "oppressed nerd" is stopped by these things becoming more mainstream. Then it's not some weird nerd thing, it's a normal thing. 

Honestly, I think you're just upset that you can't keep your previously niche interests to yourself and your in-group. The "oppressed nerd" narrative is becoming less of a thing now that the culture is being mainstreamed, so you can't feel special anymore by being the poor victim. 

If you actually cared about what happened to you, you'd embrace what's happening, even if it's not 100% genuine or doesn't get everything right. Because it destigmatizes these interests for future people.
