"I grew up in a pretty gay world - my brother's gay and he's been married to a man for 20 years, which is like 60 in straight-people years"

This quote by Kevin Smith is a funny way of expressing the idea that his sibling's relationship has been a long and successful one. He is implying that the relationship in between his bro and his partner has actually been a strong and long lasting one, in spite of the reality that they are a same-sex couple. He is also suggesting that the relationship has been accepted and commemorated by their friends and family, as he matured in a "quite gay world". This quote is a testament to the development that has been made in regards to approval and understanding of same-sex relationships, and the fact that they can be just as successful and long-lasting as any other relationship. It is also a suggestion that love is love, despite gender or sexual orientation.
