People who disagree can still have good intentions
If another parent has a rule you think is too strict, have grace in disagreement and a sense of proportion.
One of the quickest ways to anger people on social media is to even bring up the topic about what rules children and teens should be expected to follow and the restrictions to guide compliance.
So here is a general rule: If you become enraged that someone has a stricter rule for their children than you would personally implement, or has a rule you would have disliked as a child or teenager, you seriously need to get a sense of proportion. Calm down and take a walk before you start ranting in the comments.
I saw a discussion on Threads where someone asked if teenagers are allowed to have their smartphones in their bedroom overnight. Some said yes, others said it demonstrates a lack of trust, or is toxic, or would ruin your relationship with them as adults. One person even described it as "Nazi s***." (Because not allowing a smartphone in a teen's bedroom at night is exactly the same as rounding up Jews, sending them to concentration camps, and slaughtering them by the millions. Sure.)
The point of this is not whether it is wise to keep smartphones out of bedrooms at night. The point is that we are often far too quick to judge parents for their parenting choices. They are too strict, or they are allowing their children to get away with too much, or they are overprotective, or not protective enough.
But the important principle is this: Absent evidence of actual abuse which should be addressed by the civil magistrate, we should assume that we can have disagreements over parenting and both sides have good intentions, both sides love their children, and both sides are doing what they believe is best. Furthermore, different children (and different teens) have different needs and may require different restrictions or freedoms - sometimes even within the same family. We should be careful about judging each other and being needlessly divisive.
In the end, you have bigger problems than someone else's parenting style.
If you don't, find some.
