Meh. The world is much bigger than the USA. Secondly that rule makes it difficult to educate people about why patents are as bad as they are.

You can easily find examples that are not relevant to Bitcoin if you want to discuss the patent system in general.
 
Feel free to continue censoring your own discussion within closed corporate environments. But to say keeping patent discussion off mailing lists is appropriate or wise when the tech news is full of such discussion is silly.

It is both appropriate and wise. Please keep discussion of Bitcoin-relevant patents elsewhere.
