Depends on your personal reason for investing in the fortunes of the club.
If it's a daily/weekly distraction from real life and an excuse to have a pint at the weekend, yes. If it's a bit more than that, an institution for which you feel pride and respect, representing the hopes and dreams of a region that needs them, then no.
What's funny?
The insinuation that those not wanting Newcastle United relegated see the club only as a distraction on a weekend. Couldn't be more out of touch with reality.
