It is quite amusing that you think writing some words in capital letters strengthens your argument.
It is MORE amusing that you think emphasis means it strengthens an argument rather than just drawing you attention to what I feel you really need to pay attention to. Can we stop with trying to assert some feigned superiority? I have a few degrees, let's not disdain them, no?
The point remains, there are other possible explanations
No. There are not. I'm going to not use caps, but listen: The only fact you need to pay attention to is that these particular individuals die a lot sooner than the rest of the population. A scientific approach is not going to stop the outcome. You simply advocate their deaths that way.
"Let's study it." No, let's not. They are dying and we do know, per fact, that something about their particular lives is killing them off. We know it. "We don't know what 'it' is." I disagree. If you accept scriptures, you have a head-start. If not, oh well, but 'Let's study it' is the crass answer. You already know something about it, in particular, causes more suicides, more death-causing diseases, 50% of all 'sexually' transmitted diseases (here's your sign), etc. Some things are their own correlation and you simply miss it for being daft.
and those are not hard to find if you are interested). If it is so blindingly obvious that there is a direct causal link, then why are you not able to present it? Is promiscuity, not using condoms and drug use inherently homosexual behavior? (In that case, explain how same sex attraction necessarily leads to those things) Of course it isn't, there are plenty of faithful homosexual relationships where neither party uses drugs. Argue your case, don't ramble and simulate screaming in your writing, only makes you seem highly unstable.
Depends on the audience. Most people, when you say 'STD' (in this case Canada), they actually know the correlation. Oh, I'm sure some of them are transmitted other ways, but then they would be called something else by the Canada's version of the CDC.
