Bubbleybertie is clearly unconvinced by his or her own arguments.
Bubbleybertie is not bubbleymummy, nor is she me, Blueberties.
She or he is a name-changer who has to resort to these kind of tactics because, I assume, she or he has no argument that will stand up without that.
She or he does not take vaccine damage seriously or she/he would not play these kind of games.
I could easily namechange to Pimsocock but I haven't the interest or the immaturity. I also have a lot of confidence that what I have to say is worth reading without using trickery.
Pims: your "clear fact" about SSPE was not a clear fact at all. It was demonstrably untrue.
Your "clear fact" that measles after immunisation is rare, thus rendering herd immunity irrelevant, flies in the face of the pro-vaccine argument that everyone must be vaccinated for the vaccines to work -- herd immunity.
I don't think you can explain these away. I don't think talk about measles deaths explains them away, it's a specious attempt to distract attention. I think scare-mongering about measles deaths is something which you have had to resort to because your "clear facts" have been shown to be nothing of the sort.
If you condone the tactics used by the namechanger then I think you must have just as little confidence in your own argument.
