It gets derailed because the fundamental point isn't about 'a race of high elves' it's asking for Silver Covenant/other Alliance High Elves to be playable. Elves already in the Alliance since Vanilla.
No one gives a shit about blood elves in this request, but derailers will come and put the focus on that when it's not related at all to what the request is.
Not sure what's so hard to understand about it.
And no one needs to argument with you or anyone anyway. Thread is supposed to be focused on suggestions/differentiations that can make playable Silver Covenant/Highvale/other High Elves already on Alliance playable without regard to Void Elves or Blood Elves.
No different than people making threads on Wildhammer Dwarves and being told "roll a dwarf shaman there is your Wildhammer." It's derailing and not what the request is about. And guess what? Players are finally getting Wildhammer because Blizzard is finally adding the look in. Before then everyone understood a Wildhammer isn't playable, except for people who purposely are trying to troll or derail a thread.
Same thing happening here.
