I don't think that's accurate, but I understand why you say that.

The tax on suppressors (and automatic weapons) is often several hundred percent, because the legislature and regulatory agencies are not allowed (by the supreme court's opinions in the last few decades) to outright BAN them. The very high tax is pretty much the only way they have to restrict the sale of those items.

I've never heard a gun enthusiast say they shouldn't have to pay sales taxes. (Well, that's not true because there's some overlap between gun fanatics and libertarian tax radicals.)

Exempt from punitive taxes. Nobody is saying suppressors shouldn't be taxed like game consoles or dog food, they're saying suppressors shouldn't be taxed like gambling or tobacco

If there's a $200 tax stamp on blue eyes white dragons that needs to go too, but afaik now they're evenly taxed (sales tax alone). Neither are "exempt."

And they're still regulated, you just don't need to pay the $200 that was meant to be cost prohibitive when enacted in 1934, so what are you complaining about? That the poors can now have them easier? They should be entirely deregulated like France tbh.

Taxing something means it's only available to the rich
