This is actually the best objection to my post I’ve read today — and there have been many. 

There are a lot of psychos out there, and it’s why I’ll put pictures of my dog on social media, but never my daughter. 

But there’s a difference between social media activity of making friends and socializing vs voicing your views in the public square. With the former what you say makes a ton of sense. With the latter, I think it makes a big difference for things to come from a person for the reasons I said in the post.
