Here's a little analysis of the clip: First of all, the banner says "gay pride parade formally springfield heritage day", that illustrates how society puts lgbt symbolism to pander to the gays before their own nation's heritage, real life examples of this are the Biden putting the pride flag before the American on display at the Whitehouse during the pride celebration and in Britain, Union Jack flags were taken down Regent street and replaced with pride flags and Union Jack was disrectfully dropped onto the group by the workers who were hanging the pride flags. The gays chant the old "we're here we're queer get used to it", Lisa then says "you do this every year, we are used to it" pointing out that society already accepts the gays and allows the gays to do whatever they want including have a whole month of street parties dedicated to them therefore the gays aren't as much of "oppressed minorities" as people want them to think they are. One of the gay guys calls Lisa a "spoil sport" I'm not sure if that illustrates how ungrateful the gays can be even though society fully accepts them and allows them to do whatever they want or how the gays get irrationally offended when people merely point out that society does in fact accept them as if pointing that out makes one some "homophobe".
