That’s part of the issue though. Just on vaccines (as you brought it up). Firstly we didn’t do anything that we couldn’t have done had we been full members in the eu, indeed we did it in the transition period so were still subject to EU laws and regulations. Never reported like that though (unless you listen to James O’Brien of course, again, seeing as you brought it up) by the MSM and most brexiteers choose not to believe it and it is a choice. Regarding AZ, often reported that the EU banned it. The EU never banned jack, the EMA which is the only body that could have banned it only ever recommend it’s use, 10 EU countries exercised their sovereign rights (that dismisses another Brexit myth) to suspend temporarily the rollout of the vaccine while now undisputed claims of blood clots was investigated.
Stating facts is stating facts. It’s not a defence of anything and stating facts certainly isn’t embarrassing. The spreading of outright lies and misinformation by MSM and politicians alike to defend another lie (perceived Brexit bonuses) is embarrassing, too unquestionably accept those lies is embarrassing, to then spread those lies further is embarrassing.
