The conflation of gay as being both homosexual and stupid is a result of homophobia and continuing to use it as such is a conscious decision that marginalizes a group of people. Whether or not they outright intend it that way, they are using homophobic speech.

If you don't mind me asking, how old are you? (a broad range will do fine if you like). What's remarkable is that the word gay actually used to mean 'carefree' or 'happy'. Asserting that it's being used as homophobic speech is incorrect. Once again, the word is experiencing another semantic shift.
