Django's builtin removetags filter removes the supplied tags, but leaves the enclosed text alone. Sometimes you need the complete tag, including its content to go away. Example: 

<h1>Some headline</h1>
<p>Some text</p>

Applying removetags:"h1" to this html results in 

Some headline
<p>Some text</p>

while killtags:"h1" leaves 

<p>Some text</p>

killtags.is_safe = True
