Show us any study whatsoever that compares blood clotting events in two groups for the baseline:

Those who’ve had zero injections and never tested positive.
Those who’ve had zero injections and did test positive.

Without that baseline their claim that covid and long covid produces blood clots is just that - a claim.
In fact:
The most quoted study which the media uses to state that “blood clotting events are higher from covid than the vax” was published last summer and it never looked at, nor calculated, the above baseline. In fact the study never looked at any non injected peoples rate of blood clotting. What the study actually found was the the single group with the highest rate of blood clot events was the group with two injections who then tested positive. And the media sold that finding to the people as “rate of blood clots is higher from covid than the vax”.

As one journal member commented in the paper’s response, paraphrasing : what this study shows actually is that people had better not take these injections
