To be fair to Defiance, I sometimes exhibit some "Ugly American" tendencies because I think they're funny. You know, like getting confused over the Farenheit/Celsius thing, or misunderstanding ethnic or political distinctions in nations that I don't live in.
That said, and this is very similar to how I view musical critique: if you're intellectually honest, you have to at least concede that the other guy has a valid position or point.
Take the issue at bar, veils. Impeding liberty by banning something is always a decision with consequences. However, sometimes we constrain actions to create a greater degree of liberty (i.e., I'll trade my right to murder someone for a legal deterrent against being murdered). Anyone looking out for liberty and egalitarianism in this debate is clearly correct; however, they may agree with or oppose the ban for different reasons. I have done some reading on the issue, and it appears that due to some aspects of French culture (that I don't fully understand), this ban may make perfect sense towards the preservation of French culture and social norms. In the U.S., we tend to lean towards simpler interpretations of liberty: government has no place restricting one person's right to engage in a particular behavior that is itself seen to restrict liberty. Think of the massive war over civil rights: some people (Rand Paul) still think that it is wrong for government to force businesses to follow civil rights laws; at the same time, those laws obviously exist to ban many forms of discrimination which are not fully merit-based.
Progressives in the US have a major problem when it comes to prostitution: it ought to be legal, in a liberal society, to sell one's sexual services the same way that you would sell massage or artistic performance. However, prostitution in reality is mostly a form of slavery, with drug addictions, physical abuse and financial manipulation inflicted on young women. So, in the interest of egalitarianism, do we allow it or ban it? Depending on your perspective, whether you put sexual liberation or protection for young women first, you aren't wrong. You're making two really good points about a complicated situation that lead to opposite conclusions.
It's not necessarily that we never disagree, but more that we don't have much to fight about. Conclusions vary, but everyone on this board is entirely too smart and too mature to actually engage in a good, violent fight with the smart and mature person who reached a different conclusion.
That said, you're all a bunch of sub-human monsters and my country can beat up your country. DING DING!!!
