I'm not a big military booster, but I'm very glad that DADT was repealed. I feel like it's important that all options be available and having our own government blatantly discriminating against gay men and lesbians is unconscionable. Of course the government still discriminates in many, many ways (DOMA, anyone?) but this is a step in the right direction.
And my favorite comment on the whole DADT controversy:
