Good question.
But, sometimes people going door to door in dorms can be a good thing.
When I was in college, one day a staff member from Campus Crusade for Christ knocked on the door of a young lady and introduced her to the Jesus of the Bible.
She became a Christian and joined our group a few days later where we met. A year or so later, I forgot to get an absentee ballot and needed to skip school and drive home to vote. I asked this young lady if she wanted to take a road trip.
I drove 400 miles to vote for Ronald Reagan and ended up marrying the girl.
Now that is a sweet story! ... 400 miles to vote for RR and a bride!... I love it.
Plus, it balances out the negativity of this hellish freak show.
