Wow. Just finished reading the entire article. I can't believe how lucky I am to live in a free country.
In a truly free country, you would, for example, have the freedom to eat whatever you want (so long as it doesn't impinge on other people's freedoms). You would be able to have sex with whoever you wanted (so long as both parties are 'mature enough' to agree). This too, is not the case in the states. You would be able to marry whoever you wanted. You would be able to do to your body whatever you wanted. In a truly free country, you would have the freedom to do things that in today's non-free country we consider taboo, punishable offenses. Etc.
My personal definition of freedom is the ability to do anything within the realm reasonable laws. I feel a vast majority of US laws are reasonable. Maybe you don't agree, maybe you do. I'm happy & patriotic US citizen and that's all that matters!
Ok I'll bite. What laws are there in the US that restrict who you can have sex with? Laws against minors don't count as there needs to be some legal definition of "mature enough", unless you want a subjective judgment of maturity on a case by case basis.
