"Imagine you are at a dinning table and some one is telling you there are fairies at the bottom of the garden"
Harmless enough fantasy. Doesn't do anybody any harm and would generate some good-natured banter around said dinner table.
Now imagine there is somebody telling you that President Trump called Nazis 'fine people', the jabs were 100% safe and effective, there was zero fraud in 2020, Biden was in tip-top mental shape etc.
The 'bottom of the garden' folk are nowhere near as divisive and/or dangerous as the TDS folk.
They also would likely eventually admit that there are no fairies whereas TDS always double-down even when proven incorrect.
