I pointed out that your insults aren't necessary, that seems appropriate to me. I didn't say it affected me personally, but that it certainly isn't helping anyone, most importantly the OP who came here with a legitimate problem. Pointing that out is the right thing to do, has nothing to do with wanting to mediate or moderate.
You can stick a needle in any muscle and it would be IM, yes. That's it. Not "Sort of" or " counts as" or "close enough". Only in the muscle would be IM. But yes, it could be pretty much anywhere there is muscle mass, I suppose.
Sub-cutaneous is beneath the skin, so no, IV, and IM are not the same as sub-cutaneous. I feel you are somewhat being deliberately blurry now. Because some drugs can be administered IV but would be potentially disastrous subcutaneously, like our example here. The same for other routes and combinations. Not to mention, it's just wrong.
I'm not here to care whether the thread was fake or not. I am here to use what little intellect and experience I might have to help others, and get help when I need it. That is why I'm so vehement about getting facts right. HR is important, in that it is the reason we are here, in theory. So facts are important. If he happened to be faking, it changes nothing in my life. At least I tried to help, rather than just insulting him because I assumed he was faking.
I have no emotional attachment one way or another to this discussion, which would be useless anyhow. I only care about getting the facts right, so hopefully others can be well informed, and in that way perhaps give something back to a forum I've learned a lot from.
