You ran out the moment you chose to open your mouth.
You're comparing expunged criminal records(EXPUNGED BEING THE KEYWORD HERE) versus establishing behavioral patterns. There are some things that make sense from the outset. You made mention of one and that's because said criminal record is irrelevant, it doesn't hold weight/water anymore. No judge with or without a mandate to do otherwise would take such evidence seriously and make it admissible in the first place. It is one of those, "No shit, Sherlock," examples you've thrown out just to disorientate me and yet you're not. It's a cheap ploy.
When it comes, however, to the history of one's personal life, especially if it can establish behavioral patterns, it has to be admissible. Your character and the character of your opposition tend to be critical, especially when evidence runs short. Deciding what is or isn't based off of arbitrary political banter is dangerous. What's more is let's detract politics from the equation. Would it be advantageous or helpful in any way to default it to inadmissible? No. Unlike expunged criminal records, one's sexual history can still matter in given cases.
So, on that note, I've grown very weary of this conversation. Like I said, this is merely another example of authoritarians versus non and of course the former is going to argue for greater restrictions(as long as it favors their political leanings, of course) while the latter either at minimal, questions the validity of it, or outright sees it as trespass upon the sanctity of the justice system.
There's no winning these debates. I'm done. Continue to reply to me. I'm not going to bother.
