Oh FFS, grow up!  "But he started it Sir!" 

Now, to reply to your question (I can't believe this explanation is necessar but here goes anyway):  That is a joke.  It's not a threat.  However, you suggesting that you would spike someone's drink with arsenic is a threat.

If you can't return to the forum without getting involved in stupid fights then perhaps you're better off out of it.  I'm starting to regret giving you and another recent banned returnee the benefit of the doubt.

Michael.
