I think we all need more controversial subjects. I like finding out about things that are not widely discussed. I often challenge my way of thinking as well as other peoples thinking, and lot of people do find me weird in that way but I am, like anyone else, also guilty in settling in my opinions at times. I get upset too easy too and perhaps getting different perspectives in subjects will help me develop myself as a person.
I could throw some meaty subjects out there but after the recent hostile reaction I got I'm quite scared of doing it now... Don't like to upset people in any way.
