"LGBT community"......An emotive plea for an anonymous collective, whose integrity you cannot vouch for....And notably you've excluded "Q" from the equation.
If you recall, my initial question regarded "Q"... Therefore any subsequent equivalences inferred were direct at Q relative to P relative to the O.P.
Nonetheless the equivalences of past and present discrimination do present themselves, when considering the O.P......"LBTQ + topics in their history and sex education".
Sexual proclivities are, though your proclivity to be both defensive and offensive at the mere mention of the P word overbore the relevant issues.
And you did not "correct me", you merely presented an alternative point of view....To assume a position of correctability, is to say the least audacious, if not arrogant.
