Oh except my parents who don't believe in it but respects it, the rest of my family, brothers, cousins, oncles... they think this way too ( same than that guy) . I also found a lot of people not angry at it, but treating people who believe in it as so so stupid.
I am sorry you found that crazy guy!
But I give you an advice... never try to discuss with someone like that.
You will just give him the chance to throw hundred arguments on you and to get a relief from whatever anger issues he has inside.
And you will never be able to teach or give anything to someome who isnt open to receive it. So... with this people is better to just say yes or say nothing.
Believe me. As less as it afects you, as less as this people attack you for it.
Just think you are lucky to have this kmowledge and feel sorry for them and say nothing. Ahah be secretly arrogant but don't show it.
Just kidding, I mean this is not arrogancy.
But it helps to just feel sorry and to not get mad when someone disrespects you for your beliefs.
I think its ok if someone think diferently than you... but they should always respect your ideas.
When you believe in astrology also you have to acept not so much people will share your ideas or understand it because lots of people missused that cience and destroyed it.
So its necessary to learn how to not give a **** about this being something not so common or not so socially acepted.
Anyway I also think that guy was an ashole so I am happy you blocked him.
Good luck with your next date!
