Yeah, but... we have a long history of doing so.
Oh, they should be able to sure. I agree 100%. That's not my point.
I'm saying that folks who are asking if OSR is a good entry point to RPGs shouldn't expect them to be so any more. Old school games were an entry point for some people, decades ago. Don't expect them to be a good entry point, for different people, in a different time, just because of that history.
Different people, in a different time, are likely to be better served by a different entry point. If they do find them a good entry point, that is awesome. But I wouldn't put my money on it being the preferred one.
My experience back in the day was seeing lots of gamers throwing around homophobic slurs. My understanding from queer friends is that back in the day the overall culture of gamers was not welcoming.
