Love between boys,why do not people's approval?Why?
like title

I am a person who don't care about others sexual orienations.In paper,I think if two people fall in love with each other,It's absolutely a beautiful thing regardless their genders,ages,status or races.
But once I saw a same gender couple kissing in public,I felt shocked and disgusted,also realized that I still couldn't accept this yet.I would respect those people deeply in my heart,but It would take a long time to me to get used to it.This is me,a "normal" person's opinion.
There is another thing we need to concern:What the homosexual people's parents think and feel.They want their children to have a wonderful normal life; they want them to not be discriminated against by society.they want to see a happy ending and stable life of their chilren before they close their eyes forever.
finally,I would say It is adventurous and challenging that a homosxualist chose to live a real life with his(her) same gender lover,there is no guarantee of properties.most of them in the world haven't been protected by laws.they would face much more problems and challenges than heterosexual people.I hope gods bless them too.
anyway,we seldom see long-lasting relationship of homosexual couples like 蔡康永 and his boyfriend who have been staying together over 15 years It seems that It's very hard to seek a soul partner in gay（lesbian） circles.Wish everyone in this world can catch the happiness,we are all the same creatures to a certain extent after all.
