Even on the best forums in the world you still have to take the views and opinions of other members (in the nicest and preferably least confrontational manner) with a pinch of salt, especially as some can be full of blatant BS and have dubious agendas of their own.
Whilst easier said than done, it's best not to pay too much attention to the extreme views and opinions of the likes of Karen on Facebook, as I already suggested to you upthread.
