The Word 'Gay'

[lupestripe]

When did the word 'gay' start to be used to describe something bad or to be ridiculed? And isn't the repeated use of the word in this way a tacit acceptation of discrimination? The fact that the word was used repeatedly during my secondary schools days in such a negative way caused untold problems when it eventually came to accepting my sexuality. I rarely agree with Peter Tatchell but I think the overuse of the word in the playground and online to describe bad things sometimes does have negative connotations. Or am I just suffering from a humour by-pass?
