Basically, if you see anyone with that sign or similar variants, run. Get away as far as you can. Block them, report them, make sure they don't come an inch near you. This is a cruel, beautiful world, and these people are the definition of cruel. They are not okay, their methods are not okay, their thoughts are not okay, and this needs to be acknowledged.
If you ever had a run-in with these people, get some help. Please, it's for your own good, if not, for everyone who will ever encounter these types of violent people. Don't give them the upper hand with this; don't let fear or guilt stop you. It's not your fault they are like this. Do not be afraid of report these sick people to authorities, to adults, to guardians. Don't hide anything, tell the full truth even if it hurts.
Please, tag everyone you know about this and spread the message. I don't want another person to be hurt. Sorry for the dark news, my friends, but either way stay safe and have a good day.
