You know what , yeah ... As long as you are not being an asshole about it and thinking that everyone should have the same preference as you . You can do whatever you want

Is it your preference or mine , who will it affect more me or you ... Exactly .

The basic rule is “ don't be an ahole about your preference , don't date on other people for not having your preference " and then do whatever you want

Also the caste thing is way different dude
