Sorry for the constant edits with things, keep thinking of different/better phrasings or other little points. Also flat-out forgot to finish a point or two, like forgetting to mention the whole "open letters from professors" when in my head that was the main point I was going (got distracted by a jenkins build failing, my mistake). Anyhoo:
I also call certain religious attitudes dangerous and a threat to the progression towards a fairer society (the 'fabric of society', as it were), doesn't mean I'm calling for violent suppression of those religious attitudes, just an evaluation and reflection on the risks associated with an attitude or belief.
I posed open letters not just of Vice Chancellors. But I may have added them over several edits as I found them, been a sleep since then and now so don't remember. Anyway, those open letters show it's not just Vice Chancellors. Lots of regular professors in those ones.
As for that we would still have some access to EU universities, you seem arguing that they are saying the options are "no access" or "full access", but the problem is we would have reduced access to the talent and networks. Horizon 2020 and it's predecessors and successors are programs that, through their structures and centralised funding systems and such, provide encouragement and benefit for the international co-operation between universities as well as businesses that can reduce the hoops needed and impediments to jump through to set-up such co-operation.
Universities and research programs would have to go about it the longer, slower, and often less likely to get approved by all parties way. That is what losing access means.
I think we're somewhat buggered, because we'll always be seen through the lens that we are just the European versions of American revanchism. Everyone hears us chant "Johnny make Great Britain gr8 m8" when we say "there is little hope for the future of the UK or our leaders."
Problem is, if you go onto facebook there are a disturbing number of people who are basically chanting "Johnny make Great Britain gr8 m8". The Express, The Sun and the Daily Heil haven't exactly gone out of business either, and keep selling copies basically pushing that exact line (with all the xenophobia and racism embedded in it's meaning). It's hard to not take that view when people other than the newspapers seem to be going out of their way to reinforce it. You can argue vocal minority, but I don't know anybody who doesn't have at least one family member who is part of that vocal 'minority'.
