Your complaint is one of the most profound differences between a guy and a man.
The unfortunately all too common assumption that all males are the same and are only interested in fucking, sports and cars, stems from the guys that you are describing.
And there are so many of them.

(Note: There’s absolutely nothing wrong with the named interests, only the fanatical over-consumption of them. With perhaps an exception to fucking.

DesertDom did bring up a good point, and I understand and agree with his logic, but I do have a counter argument:
Yes, if you’re on a sports forum people will likely bring it up as an ice-breaker, but you’re dealing with a non-personal subject.

If you’re on a dating forum, talking to someone for the first time, bdsm forum, you’re on a very personal subject, and that subject does deserve at least a little respect.

So in response to your question, Bambina I wouldn’t be angry and I would accept that there are many different type of people in this world.

Just keep an eye out for the ones you want to be associated with.
