Here’s a general rule for everyone to follow:
Stop getting annoyed by what others post on FB or taking others’ posts personally. No one is forcing you to log in to FB. And no one is forcing you to read/view these posts. If reading/viewing someone’s online posts is bothering you, stop reading them. Remove them from your newsfeed. That is under your own control. In all likelihood you’re not really part of the intended audience. People post what they want to share and what they think others will find interesting. There is nothing wrong with that, especially when you are sharing what is important to you. It is really silly to get so worked up over such small things and to make a big deal out of them.
