I think sexual and bias based violence would be the worst

Violence. That was the only thing that ever upset me in a film. Still does.

Apathy

Who the hell would think watching a sex scene would be more damaging than violence? It wasn't that long ago we all shared a one room shack with our parents and siblings. Unless you're talking extreme pornography? That wouldn't be healthy for young developing minds. Most of us heard our parents having sex when we were kids. At the time it might've made us feel sick but I don't think there were lasting effects.

Drug use. Sex and empathy should be taught at younger ages. I’m all for legalizing drugs, in spite of being against using them personally.

This is tough. I chose violence but if drug use is being portrayed as cool it makes the choice harder

How about corruption? out of the choices though violence

Acts of sexual violence, sex is natural (even if it is uncomfortable to watch in the presence of your children) violence is not, explicit violence is the european censorship concern not sex. An act of love can be empowering but an act of sexual violence is always an act of degredation and it's important that the two are never conflated.

Depends, yup, Depends; especially if they're full.

By definition, an "R" rated movie is not suitable for viewing by children. So, what is your point? Do you want "children" to be allowed to view "R" rated movies because you think that they cannot/will not be harmed/traumatized by viewing the content?

Recall having this issue when my daughter was younger. My ex deemed it appropriate to have our 8 year old see Passion of the Christ, which I understand is quite violent. I would not have done that.

Any Kardashian.

A mass shooting due to inadequate gun regulation.

Violence can be explained and you can find it in almost any form of media including news programs. It can also be used as a teaching point about the appropriatness of the violence. Parents still need to discuss the movie with the children after so that they understand context. Domestic violence though would be unacceptable.

Sex is a natural function in most reporductive creatures. Again this is a matter of need for discussion. If the child is brought to understand that it is conesentual sex is natural, the less embarrassed they will be about it and some studies show that leads to lower teen pregnancy and STD rates.

I marked drug use, but anything can be turned into teachable moments. But for me its the worst thing of the three they could see. Course I'm not a big fan of Pharmaceutical commercials on regular tv even.

But that's just my opinion

Violence definitely but what if the plot needs it to be there?

Ben Affleck acting.

Breastfeeding. They might feel a sense of loss.

Violence, definitely violence.

Bad acting.

Sexual violence.
