Actually, I wouldn't care that much if my kid were in bed, sleeping, and my babysitter (that I know and trust) sat downstairs (where they would normally sit babysitting) and had a few tokes. Because I know it isn't that serious and doesn't do all that much to you besides make you hungry and think a little differently. It's also mildly mentally addictive, but has very, very little physical addiction involved - not the same with alcohol.
If you think weed should be illegal, then you should logically think alcohol and a lot of RX drugs should be too. Alcohol is so much worse in so many ways. Again, you really don't know what you're talking about, so please stop the ignorance. You sound very silly.
