ACK.

The problem of statements using a relation like ”is supported in” (IMHO 
better: by) with ranges like “*major* browsers” is that it is deferring (no 
pun intended) the truth value of that statement to a subjective definition 
for “major browser”, making the seemingly objective statement actually a 
subjective one.  The “all” quantifier of the relation then merely adds to 
the subjectivity of the statement.

If W3Schools.com would not consider Opera Browser a “major browser”, which 
would therefore not be an instance of the subclass of “major browsers” (and 
one can easily make a class definition based on the property of market share 
so that it would not apply to Opera Browser), there is a probability greater 
than zero that under *that* interpretation that statement is correct.

Therefore, arguments of that kind are informal fallacies:
