"And I do want post-metal to be in the infobox, and it's a genre less debated and controversial with the band playing it right now . . ." No it isn't, that's been roundly contested in the previous discussion.

" but this was supossed to be a temporal "middleground" solution . . ." No, it wasn't. Consensus was against you. You're the only one who considered it a stopgap solution.

"if you had a problem with nu metal being removed you should have said it, in contrast you remove the discussion template and didn't even tried to add it back nor said it here" I didn't discuss nu metal's inclusion because the discussion was about post-metal and I wanted to keep things focused. I had actually toyed with starting a new section to discuss the inclusion of nu metal once the previous discussion wrapped up, but passed on it to focus on other work on Wikipedia in the meantime. Me not raising an objection to something isn't silent consentI tend to either clearly agree or disagree with something. What a lack of comment means from it is I most likely became busy elsewhere.
