While I've certainly been guilty of going on long shot dates, I feel like your process should filter out most people with that level of incompatibility.
I'm sure a lot of people picked up on my nerdery from my profile or initial messages and passed, and that's probably the right choice.
Though I do remember one bad date, we were talking about rom-coms and I mentioned dragon age inquisition and how I liked some of the romance plots in kt. She said something like she "thinks I live too much in those games". Disaster averted, and now I have a fun story.
That could be a factor. My perspective is limited to one of a man who doesn't date men. I had some nice (and one memorably, laughably bad*) dates with queer people on hinge, but it wasn't my primary experience.
