i hear it another way, but I'm the same vein.
"they" are accusing potus of treason. that is the issue. the seriousness of that claim followed up by a lack of evidence.
the claim of reason isn't treason. saying i suspect someone of treason isn't treasonous… calling that claim treasonous undercuts our ability to think critically about what is happening and pushes is into an endless loop (your claim about my treason claim being treason is treason!) lol.
it speaks to their desperation. and he caught them all.
