sravna, I think you are not fully grasping what "deviant" means. A deviant is one who deviates from what is widely accepted as "normal". In India, driving on the left side of the road is normal and therefore, anyone who insists on driving on the right side of the road is a deviant.
If we take sexual behavior, there was a time when most couples had many children, 4 or 5 at least. Now, even from my generation, it is hard to find a middle class family with more than 2 kids. This, I assure you is not because they are doing it less now, but because they are doing it for pleasure and preventing pregnancy using some sort of birth control.
All of these people don't see anything wrong with this, it is considered "normal". To you on the other hand, any sex not intended for procreation is a perversion. This makes your stance abnormal, i.e. deviant. So, the above diagram you have shown, one in which "no sexual interest" as the opposite of what you say is "deviant" is absurd -- "no sexual interest" is as deviant as one can get.
Recent polling in the U.S. shows 53% support for Gay marriage, a clear absolute majority. This clearly shows homosexual behavior is not viewed as deviant in the U.S.
An
unscientific poll conducted in India a year ago showed 31% support for Gay marriage with 69% opposed. This poll only represents mobile social network users, if that, who are probably predominantly young people. At least in this group, homosexual conduct is not seen as deviant, a conduct that is supported by 1/3rd of the group can hardly be deviant. Just one year prior to this poll homosexuality was illegal in India. Give it another 4 or 5 years, with more young people coming of age, and more old people kicking the bucket, the support is sure to rise and even cross 50%. Give it another 20 years or so, then, a day will come when opposition to Gay marriage will be viewed deviant.
Cheers!
