Francisco, I'm pretty sure Bishop Williamson is just tired from the travel strain.
Because in the beginning of this month the good bishop was in excellent shape.
See for yourself in the following video in two parts. It shows a home fixture of the English Lion. One great hour of lecture at the London Forum :
Main part:
Extra Min:
Around the 6th minute (+/-) he gets so angry with one of the few liberals in the audience that he nearly gets into a fistfight!
What a bishop!
(Most listeners are not yet Catholic, it seems, but for sure they invite the good bishop to learn something from him, so they're open for the truth and willing to think about it! Whilst 90+ % of the so called traditional Catholics betray this good bishop.)
"Liberals are rats!"
... direct quote from the bishop during Q&A at the London Forum. Doesn't sound very tired... :-)
