Christians is this the reason why you think being gay is wrong?

im a christian, and i do believe ity is wrong, if i didnt i would be a hypocrite, if you believe in god or mother nature, man is not meant to be with man, our bodies tell us that, and if you say its ok for one man to be gay then its ok for all, and if we were all gay 200 years ago we would be extinct, having said that i dont want to tell people how to live their lives.
