There is quite a leap from Russian anti gay propaganda laws to boycotting the Olympics. Many people would argue that laws supporting any kind of torture or the death penalty are human rights abuses so should any and all countries practicing those laws be forbidden from partaking in or hosting something so arbitrary as the Olympics?
I'm not arguing that this wouldn't be an effective way to get the Russian government to go back on some of the recent legislation, but then why stop there? Can we use this tactic to stop drone attacks, decriminalize marijuana and improve women's rights in many countries?
No we can't. Because this isn't a genuine movement designed to change Russian public opinion and laws, but a simple us=enlightened you=backwards monsters campaign.
