I'm outside the L postcode area, just, but I've been to plenty (dozens) of games over the years as I'm on the ball on ticket days and the like.
Since this policy is only for "extra" (unsold) tickets (important! it's not "total" prejudice!) I don't find it too bad. I'm scouse by birth but not there for work purposes, haven't been for years now.... so I like "my" seat going to true, local reds, I just hope the bell ends who leave early, take phone videos, refuse to sing etc. get whittled out. I won't feel entitled, as I don't feel I'm missing out. I think we all want a reduction in the class of people who do what I just described; they shouldn't have tickets above true reds, but how can you police that?
I accept being "second tier" as I'm not in the area. It's Liverpool Football Club.
Overall that policy might be a decent compromise... if you're an OOT, you can go, but you have to be sharp with membership registration, buying tickets on time etc. If you're a local you can relax a bit comparatively, but I'd still suggest being sharp. I wouldn't say it's prejudice - I'd call it preference.
I'd err on the side of caution anyway to be honest. You have to try your best and you have to voice your concerns or the club will be none the wiser. Of course the ticket process online leaves loads to be desired.... plenty of gripes to go around. But it's about supporting the team, and for that reason I think probability suggests locals = better support. Though my worst experiences have been with aul arses who do fuck all but moan.
