I believe people can change. Anyone, in any time of their life can change, but only if they are willing. The problem lies in the fact that most people are not willing to change, they are, instead, trying to change you.
I have tried to reach through their mental barriers, but words only push so hard. I tried to show them videos, certian circumstances, I even took a stand against an entire community, risked relationships with people that I love, people who looked up to me, people that were important... But, I guess, not as important as the big picture I see.
They will always refuse to see my picture and rather show me theirs. I listened, I watched, I read, and I submerged myself in their world, and tried to see what they saw... And I still said "no".
So when I try to do the same, I am not even aloud to bring it up anymore, unless it's from their relm, because they are cowards. They want to believe, not take action. People are timid to bleed, to cry, to feel what another feels. The truth makes them cringe because they don't understand. They don't want to understand. So therefore it's wrong, or it's right, or it ceases to exist.
Change requires action.
I hope you're comfey in your chair.
