As Tim said:  You are not only affecting yourself but by default every 
other user of the Internet if you get infected with a virus/worm/trojan 
horse/spyware.  SELinux is designed to prevent that level of stupidity.  
Sorry, but you have to read through several RFCs to understand your 
ability to screw things up royally when you are on the Information 
Superhighway.  Please take time and read RFC 1087.  It basically spells 
out YOUR responsibilities when driving there.

Now, you are free to take your 'payed for' toy, take it off of the 
Internet and do whatever you want.  At that point, it becomes your 
problem.  Otherwise, you should obey the 'rules of the road' and make 
your system as secure as you can.  I do.  I've disabled flash on my 
browser.  I've blocked all sorts of ads. Why?  Because both are vectors 
for malware.  I don't like rebuilding my systems, but if they get 
infected with someone else's 'stupidity' then I'm out hours of work that 
I won't enjoy doing.  How would you feel if failure to use SELinux 
infects hundreds if not thousands of systems with a virus?  How would 
you feel if not using SELinux saves your work from being inadvertently 
destroyed?  That is why it exists, so stupid people don't do stupid 
things.  Again, you are free to do what you like as long as it will not 
affect others.

Now, if you are trying to do something that you SHOULD be able to do, 
and SELinux will not let you, the SELinux people need to know about this 
and provide either a permanent solution or a work-around.  They should 
not allow you to do stupid stuff with your system when it is on-line and 
connected to the Internet or any other type of network.
