Religion is good, but not to be followed blindly

I've heard of Dr. Laura Schlenssinger. She's one of those Dear Abby types.
I've always advocated that one should have their own religious faith, but bearing in mind that the main religions in this world started propagating more than 2000 years ago and not all of their rules and regulations should be applied strictly.
If we follow the line of reasoning as per below's story, then it means that I "own" my Indonesian maid?

"Why Can't I Own a Canadian?"

Dr. Laura Schlessinger is a radio personality who dispenses advice to people who call in to her radio show. Recently, she said that, as an observant Orthodox Jew, homosexuality is an abomination according to Leviticus 18:22 and cannot be condoned under any circumstance.
The following is an open letter to Dr. Laura penned by a n East Coast resident, which was posted on the Internet.
It's funny, as well as informative:

Dear Dr. Laura:
Thank you for doing so much to educate people regarding God's Law. I have learned a great deal from your show, and try to share that knowledge with as many people as I can.
When someone tries to defend the homosexual lifestyle, for example, I simply remind them that Leviticus 18:22 clearly states it to be an abomination. End of debate. I do need some advice from you, however, regarding some of the other specific laws and how to follow them:

When I burn a bull on the altar as a sacrifice, I know it creates a pleasing odor for the Lord - Lev.1:9. The problem is my neighbors. They claim the odor is not pleasing to them.
Should I smite them?

I would like to sell my daughter into slavery, as sanctioned in Exodus 21:7. In this day and age, what do you think would be a fair price for her?

I know that I am allowed no contact with a woman while she is in her period of menstrual uncleanliness - Lev.15:19- 24. The problem is, how do I tell? I have tried asking, but most women take offense.

Lev. 25:44 states that I may indeed possess slaves, both male and female, provided they are purchased from neighboring nations. A friend of mine claims that this applies to Mexicans, but not Canadians. Can you clarify?
Why can't I own Canadians?
