You trolling.
BTS took on the school system, the government, and social treatment of young workers, and they CAUSED CHANGE. "BLM for promo" lol, they donated to charity, what do you want them to do? Look up their group donations and the various members' private donations, they donate to charity CONSTANTLY. And ARMY donates to charity in their name. Since the 9th, ARMY has donated 132,000 USD to a hospital for kids in Yoongi's name in honor of his birthday, plus dozens of other projects. What has your fav done lately for social causes?
You clearly are a child so this one time I won't be too hard on you, arguing with kids isn't my style lol. If I tell you who my faves are you're gonna have a hart attack probably... I'll let you guess. And I'll let you read my post again. It starts with "Bighit marketing BTS as a woke socially aware activist group when those guys never speak explicitly on any social issues, you for some reason replied with something that has nothing to do with my post. So go read it again lol.
What change did they cause? They don't speak on social issues. They avoid the topics of racism and homophobia except saying 1-2 bare minimum sentences. They didn't 'take on' anything, they're simply writing songs, they're one of the MANY musicians in Korea who have talked about the things you mentioned, and a lot of them brought more awareness to it than BTS. Mental health, LGBTQA right, racism - many artists talked about this. ACTUALLY TALKED, not just said 2 words. BTS mostly write about them because Bighit knows these topics attract young fans. The survey Bighit did where they ask fans personal questions about depression will tell you that lmao. Bighit uses mental health and social issues as promo. Just facts here nothing else.
They donated to charity and? Millions of people do so? Almost every idol ever has donated to charities, you know that? Some of them donate more than BTS. Do donations make them woke legendary social activists?? Btw their donations aren't private, the media always writes about them. Again this has nothing to do with my post.
Yes, they did use BLM for promo, it's so obvious only total idiots still deny it lmao. It was brought up in every interview for no reason like they did something heroic, Bighit still uses BLM and their performative donation to promote them, BTS and other 2 groups donated exactly at the same time and tweeted about BLM at the same time, then had their 'heroic' action and kpop stans' 'activism' (aka spamming fancams) praised on American TV the next day 
So unplanned! Not intentional at all lolol. BTS were silent about protests for days, everyone was asking them to speak up and raise awareness. They kept ignoring it. Tweeted only at the last moment. It was a planned promo honny. BTS kings of social awareness <33333
Armys were bullyng Black fans and everyone who was asking BTS to speak, and donated only after BTS did. Then started to bully Black fans again shoving their performative donations in their faces. Armys don't give a shit about activism lol. Oh besides, the organization BTS donated to has nothing to do with Black lives, none of that money went to victims. If they really cared they would research it. (:
