We really don’t know every user on Facebook and we are also unaware of how dumb some people on Facebook can be. These people are so stupid that even you’ll be dumb after reading their dumbest posts on Facebook.
If I’m right, then these ridiculous Facebook posts haven’t yet appeared on your newsfeed and you should be really thankful for that. Once such posts start appearing on your newsfeed, then it’s truly time for you to block them out.
