It's not about people's sex lives. It's about the process by which laws are made and the powers the people posess to control their own lives. Each state that has a law about sodomy has a method by which that law can be altered of abolished. The general trend is to do so. But this decision subverts that whole process and gives it to unelected judges.
According to the constitution, the federal government can do only those things that the constitution says it can. All other powers are given to the various state governments unless the constitution forbids the states from doing certain enumerated things. No where in the constitution is the power to regulate sexual activity given to the federal government. That therefore is a state power. If you have a problem with the sodomy laws in Texas you can work to get those laws repealed or changed, or you can move to another state that does not have those laws. By taking on this power, yet again, the federal government moves to increase the amount of power held in Washington and lessens that held in your state capital. Yesterday it was gun ownership. Today it is sex. Tomorrow it will parental authority over your children.
You should not dismiss this ruling as a ruling about sex. It is not. It is about control over power and who wields it.
Read further into the thread. This argument will not win the day with cherrycapital.
He or she believes in rule by an elite few, preferably libertaraian and libertine.
