Homophibia

It is not news that there has been a rise in homosexual relationships within social circles in the country, hell most of my friends are queer if not curious. Some people myself included have assumed the position that what doesn't hurt me I shan't condemn, right? However, there are still a lot of straight people who even have partners who are always quick to slander and smear these people and it has got me wondering, where is the hate really coming from? Also, what could be behind the sudden spike in same sex relationships?
