Lot's of platitudes and razors say "hello" frequently. The thing that those that like to retreat to pointing them out seem to miss is this...
they are not a law
nor are the always applicable...
Sometimes they are useful...
Other times they are simply an escape hatch used by the mentally lazy to justify engaging mental spam filters...
EDIT: In respect to Godwin's law in particular...
It does indeed tend to be a trend.
That doesn't mean in some cases it may not be the truth.
