I guess the bigger question is . . . .
The bigger question is not why we are "allowing" someone to praise Nazi symbolism. If you're advocating extrajudicial violence, there is no bigger question. You're the one who's out of line, and you're the one who's a threat to the liberty and safety of your fellow Americans.
It's like the people who have murdered abortion doctors. They oppose abortion like I do. However, once they decided to carry out violence, the fact that they may have been "right" about abortion is of no consequence. They're out of line and worthy of prosecution to the fullest extent of the law.
why are we (you, me, et al.) allowing anyone to praise any nazi symbolism. Richard Spencer and his crew were doing the nazi salute in DC with no repercussions.
Oh, I don't know. Maybe it's the same reason we don't have national churches, slavery, quartering of troops in private homes, etc. The Constitution prohibits imposing "repercussions."
Trump was accepting white supremacists support and acting like he didn't know who David Duke was and not disavowing this support. If we (you, me, et al) don't stand up to this fascism it will flourish.
"Standing up" has its limits. Speak out against Nazism? By all means, do so. But once you advocate violence, you're off the mark. In addition, as terrible as it is, fascism isn't the only dangerous ideology, and it's not even the most imminently threatening.
Here's what also gets lost. Nazism isn't difficult to discredit. There's a reason why it has few adherents. However, if you act out in violence, you lower yourself to the Nazis' level and actually lend Nazism a degree of credibility that it doesn't deserve. Of course, your Antifa people don't go along with this, because most of what's wrong with Nazism is also wrong with their ideology. However, a generally fair-minded (if somewhat misused) guy from Mobilhoma should know better than to align with either group.
