I am too. I don't have any especial malice towards purists who cosy up to Death Eaters, but I do concede to an "if you lie with the pigs, then don't be surprised if you end up dirty" take on them.
Yes, I believe that the bombs were intended to distract rather than seriously injure, so perhaps something went wrong there - although that social group is known for their hyperbole, so I wouldn't take every single thing said on the network at face value either.
I don't believe every purist is an undiscovered Death Eater - I know of a few who simply wouldn't have the wherewithal, or even the desire to be one - but I personally draw a distinction between people who simply may have been in the wrong place at the wrong time (in the case of the Mabon attacks, or at the Quidditch game) and those who knowingly cozy up to murderers, whatever their motivations, and who believes someone else's life to be worth less simply because of how they were born, and that imprisoning such people on patently false charges is fine. That is my opinion, however. I am enough of a big girl to bear it if you don't agree with me.
More importantly, I do concur that in the case of other acts - such as a possible on Diagon to free the Wandless - we need to work to minimise civilian harm, so we are both on the same page there.
