Does supporting gay rights mean that I am a gay?
No, It means that god has not done any fault by making you a human being as you are capable of using your mind properly to understand the thoughts, mindset and pain of other human beings with different sexual orientation.
It means that you are not selfish and Orthodox who can't think beyond his personal needs & cultural Barriers etc, leave aside understanding and supporting a different thing which he don't know or experienced.
It means that you have the power to understand and digest the perspective of others and guts to support it also.
It means that you believe in diversity of thoughts, mindset and behaviors of different human beings which is actually a creation of God.
I feel that atleast we shouldn't reject or criticize what we don't understand or which we have not gone through if we can't support it.
