I completely understand it from the other side. I'll admit that I see other guys do "stupid, childlike" things and make a judgement on them, considering they aren't "sensitive" to the person they just hazed.
But I can tell you this, without a doubt. When the child is beaten from us... we aren't ever the same... unlikely to be enjoyable company.
Guys need to find a way to be playful and not hurtful. But sometimes... we just can't help ourselves in that moment of spontaneity and opportunity.
No different than a girl crying when she gets hurt. That's just so unnecessary.
I understand that there is plenty of opportunity to agree to disagree on this (from any male and female position).
The reality is, like every and any way that we are all human and all the same, in these way most will never truly understand the other side. So it's a matter of accepting and respecting those genitalia differences and not expecting the other sex to be more like us.
Tolerance is one of those great, underused virtues.
