I've always imagined that yes, he did do certain abusive things.
But there are many degrees of abuse.
I imagine that whatever MJ did was at the more innocent end of what society now disallows.
Of course, I may just be blowing smoke here. Frankly, I haven't any real clue of what may or may not have happened.
I also think that political correctness has gone a little too far.
When I was young, I had many really satisfying and nurturing friendships with teachers and other older men. None of them were in the slightest degree improper -- and nowadays, none of them could happen. No teacher could take the risk of misinterpretation or even outright lying.
I think it's a shame.
We were far too oblivious, a couple of decades and more ago, of the possibilities of abuse. A line had to be drawn. But to my mind, we've drawn a line that is too firm, too wide, and that throws the baby out with the bath water. The possibilities of certain bad things happening have been reduced, but so have certain very good possibilities.
The pendulum must swing back a bit.
Please understand, I don't mean to insult or sound insensitive to anyone who has suffered serious abuse. If that happened to you, you have my sympathy.
