What about you say one thing but mean something different?
"It's not racist to be worried about immigration" - basically an excuse to be racist towards immigrants
Or
Or a recent one from the UK, "I agree with Just Stop Oil, but I don't think they're going about it the right way"
- When you basically just want JST to go away so you can drive your SUV around in peace
This is a bit of a tricky example, if Orban or Meloni said that I'd be suspicious.
But if an environmentalist or leftist criticised bankers for investment in fossil fuel or the 2007 economic collapse then it's obviously not dog whistle to blame it in international bankers.
