I had similar problem, I listen to many lectures in my free time to the point I become knowledgeable about many subjects !
When I meet people I talk about many things and sometimes I challenge their major, and they get upset and sometimes I get to fight with them !
One day it almost got to calling cops at me, that moment I had to put hard stop to talking with people ! and keep it to me self~
Reading books or listen to lectures is not a problem, I just dont have someone to talks about many different things ~
