I was going to post this right after the episode in question, but I decided to wait a little bit to diminish the chance of spoiling it for people who might not have seen it when it aired.
I am not terribly politically active, so I don't talk about gay discrimination very often. I'm aware it exists, and I'm aware it's a problem. I simply feel that the best way for me personally to combat it is to be the best person I can be, and answer whatever questions people may have about what it's like to be gay. I figure that a lot of the opposition that people have against the so-called "homosexual lifestyle" stems from a lack of knowledge. The fact that I'm sexually and romantically attracted to other men doesn't really make me very different from my peers, and I figure that I can demonstrate that better than I can explain it to people- so I try to go about my life normally and not spend too much time as an activist.
That said, it does get lonely every so often. I see my friends go through boyfriends and girlfriends, and I see them enjoy their relationships without thought. I see them walk through a heteronormative world without a thought, and sometimes I envy them. I am very comfortable with my sexuality, and I wouldn't change it even if I had the opportunity, but every now and then it becomes obvious that they don't have to think about some of the things that I do- whether or not PDA will offend someone (and I'm not talking about making out in public, I'm talking about simply holding hands), whether or not they can invite people to their wedding without causing a fight... there are others, but those are two pretty big ones.
One of the things that had kind of bothered me before was the fact that there were so few gay characters on TV. There was Will & Grace, but that show's not on the air anymore. There are Mitch and Cam on Modern Family and although I love them, they aren't exactly characters I can immediately relate to- they've already started a family. There might be others, but I don't watch that much TV, so if there are I had never been exposed to them.
I felt so immensely validated when Kurt came out on Glee. Watching him go through his challenges was a great experience, because having such a prominent character on such a popular show sort of said that gay is a normal thing to be- which is a fairly new sentiment in the public arena.
When Blaine and Kurt kissed in the most recent episode, it was kind of a culmination of all those feelings.
For these reasons, I proclaim Blaine and Kurt to be the Best TV Couple Ever.
