It's not getting worse, and definately improving slowly but surely..
Much like racism, I predict that eventually pretty much 99% of people will be completely accepting of homosexuals sometime this century... Homophobes will get over their rediculous insecurities and irrational fear of gay people as it becomes a normal thing and not so 'new' (I know it's not new, but its only in the past couple of decades in most modern societies that its actually become 'okay' to be gay.) And similarly, most of the haters will move on to hate on some other minority. Religious extremists will remain the same as they are now, but shut up about it because voicing it will be likely to get them enemies. Gay couples will be able to get married or an equal kind of partnership in virtually all western societies and most other places too.
Perhaps it's less of an honest prediction and more about what I sincerely HOPE happens. But honestly it looks like it's going to go that way from my view point. It's just scary for some people because they don't understand the details yet, and 'discusting' because manly straight men have to say that in order to keep their cred and not get punched. This will all change in time as homosexuals become more accepted. It just takes time for these things to happen, I again give racism as an example... Let's just be patient.
And yeah, when people call things or other people 'gay' its usually used without them really thinking about it much. Sad, but its not too big of a deal. It's just a stupid fad that will die out, and theres no hatred behind it really.
