I agree with you, but in practice it, the method in which the tags are
removed will play an important part in whether what you say is even
possible.  If the < and > are replaced with character entities &lt; and &gt;
then you can do what you have recommended.  If the intent is to actually
*remove* the offending code, then what you recommend is not feasible.

A person, for example, may be trying to show a simple mathematical proof in
the text area, such as:

if a<b, and b<=c, then a<c

Such a proof would probably break the stripper, or would get removed from
the input, which is probably not what is intended.  Dunno, maybe possibly
offensive code is sent to someone for review before it is posted?  Just a

tags, rather than eliminate the "unsafe" tags.  Then you have the unknowns
covered as well..
