You forgot this part: "unless the person asks"

The reason people post obituaries or bios on social media is asking for support and wanting to share with others all the wonderful things about the deceased they are going to miss.

Before you say it's for logistical reasons, it isn't. Family and other close friends who will attend services get the service info from texts, calls, emails, etc..

Ironically, one way often suggested to deal with social media posts you don't agree with is also "don't say shit" lol, if you're ok with ignoring that tenet why should I ignore my friends' grief?
