Huh? Too much discrepancy between the quote and the response. Disregarded until expounded upon.
Under the assumption that the information is true. If, however, it's irrelevant to the subject matter, why bother? Many historical figures have books or other documents or evidence focused on them (which, I'd assume, is how they're adding these facts in the first place). The information there hasn't been altered, and is very much public. If it's important that the students know who was gay or straight, it shouldn't be hard for them to find out themselves.
Was there enough opposition to keep the bill from passing? History belongs to the victors, as it were, and that's something to watch out for. If those against the additions cannot reasonably deny the information being added, then there's no problem calling it fact.
Ack, pardon. That was a mistake on my part, my phraseology getting away from me. I'd retract the sentence, but I hate inconsistency in quotes. Instead, I shall kick myself.
Perhaps not quite as many as you think. I did state and highlight "If" when referring to the contributions of gays. It's not hard fact, but something I rather deeply suspect.
I tried to come up with some specific sources I could link you to regarding the ways homosexuality is treated in school system, but I haven't located any actual sources through Google-fu. Only reports by bloggers and other sources I think won't be seriously regarded. So I won't be able to back it up this time. Maybe I'll return to this particular subject, but the chances are I won't. It's all I can do to apologize for the lack of supplemental material for my arguments and to continue to be resolute in my opinion.
