The "rest of the world" is quite welcome to laugh. As citizens of the United States, we are largely here because our ancestors disagreed with yours about how things should be done. I see no reason to be concerned about a similar difference of opinion a few generations later.
I don't find myself overly concerned with the opinion of the "kids of the future", although they will inherit the rights that we defend for them today. Countless people have sacrificed and died for my country to ensure that I had the rights I enjoy as a US citizen. I think that refusing to stand up for those rights would be a poor way to commemorate their efforts.
The issue at hand here may be small, but all big things usually start out small. Assuming that things will never get any worse and trusting to blind faith just isn't in my nature. The great thing about living in the US, is that the laws are determined by the concensus of the people. If enough folks disagree with my viewpoint then I'll find myself legally constrained to accept such indignities. Unless that happens though, I'll continue to find myself protesting in good company.
