Really? Because yesterday the PRESIDENT OF THE UNITED STATES defended white nationalists and neo-nazis on national TV.
This discussion also shouldn't have much to do with free speech. If private companies do not want to allow pro-nazi websites to use their servers, they should be allowed to refuse them.
The only slippery slope here is the idea that Nazis are dying and there is no need to take them seriously. People in Germany did not take them seriously when Hitler started his rise to power, then the country fell into disarray and Hitler had simple answers to hard questions. After everything that has happened over the past year, it is time to stop thinking that something like Hitler's rise to power could never happen again. We are in uncharted waters.
