How can you educate your kids about strangers now? 2020

So not sure how to handle this stuff up now, I want to telll my Kids about the dangers of strangers and to look out for them when out but since the rules changed i'm not sure whats socially acceptable

I was planning on telling them to stay away from:
- Drag Queens / weird looking clown women going to their school
- Thugs burning stuff up or protesting violently
- Democrats who act like they are their friends - used to show them pics of John Podesta or Joe Biden so they could stay away from those


Is it still socially acceptable to give them this advice? Most of this people are apparently role models now according to the majority of america

Thanks in advance,
