Not really sure what you mean by "all marriage equality" there Frankie boy but I hazard to guess you mean<quoted text>
Anything but substance eh, jackass? When you're done with your petty personal attacks about "obsession" and such other stupidity perhaps you'll finally get on topic?
Don't you agree that the judge overturning California's ban on same-sex marriage bodes well for all marriage equality?
The question is not off topic. But I bet your response will be.
1. Marrying children
2. Marrying blood relatives, i.e. mom & son, father & daughter, brother & sister.
3. Marrying your pet.
First you are using the slippery slope fallacy. But just to answer your stupidity.
1. There is thing called AGE OF CONSENT. Children can not give their consent to sex and marriage. ergo it will remain illegal.
2. Therre are health issues with marrying close relatives, which is why it is illegal. You can easily see what happens by studying British and Russian royalty in the 1600-1800's, particularly the Tsar family, you will notice the high rate of hemophilia. And that was with cousins marrying cousins. No telling what would have happened between direct family members...well I take that back...you are a prime example.
3. Besides from the obvious health issues, animals can not give their consent to marriage....so it would be rape.
4. marriage above all else is a social contract. Inheritances, medical decisions, etc are all part of that contract. With polygamy, the lines of who gets what, who makes what decisions are blurred and lead to legal battles. Does one of the wives who is not the mother of one of the children in the marriage get to make medical decisions for that child is a prime example of why polygamy is illegal.
These are all rational, logical reasons why the slippery slope fallacy is moot. However, judging by your previous posts, intelligent logical debate is not your forte. Debating with a wall has better results.
