I don't see that it's condescending. I just think it reflects a realistic assessment of Batley's chances of competing successfully in the same league as Wigan and Leeds.
I think having a professional second tier with clubs not wanting to go up is just fine. There's no reason why every club should want to, or be allowed to, play in the top division. There is a role for clubs of all sizes.
The RFL could certainly try and help NL1 clubs reach SL but I'm not sure that even Richard Lewis can suddenly rustle up 50,000 extra people to go and live in Batley.
Some clubs are small. It's a fact of life. The key is to help small clubs that are constrained by their location become better small clubs, not to dream of them becoming big clubs.
If RL does not have a second tier with everyone jostling to go up, I don't think the game is progressing. Imagine if Blackpool refused to go into the prem at soccer. I don't think it is healthy to have clubs with no ambition to go up (perhaps because they aren't incentivised by the RFL). It is also partially preventing ambitious clubs from winning trophy's
Regarding your comments about Batley, I note on a West Yorks map that there are no SL clubs south of the M62 and West of the M1 barring Huddersfield much further south, and the likes of Liversedge, Tingley, Birstall, Cleackheaton, Heckmondwike, Hightown, Bradley and Mirfield could well opt to support Batley. I would guess that is a few hundred thousand. Not a small club then, eh?
I can now see why you wouldn't want Batley in SL. Perhaps you see that territory as potentially Huddersfields?
