If you really support bitcoincash you should go outside of /r/btc to spread the knowledge about it in other subs/forums too

Lots of mainstream subs have related topics discussed frequently and BCH is very under-represented in these threads as I see it (lots of brainless BTC bagholders tho).

While it's important to educate people who somehow end up on /r/btc preaching to the choir here won't do much.
