The conservatives still have power in the UK and will continue to have influence for the foreseeable future. As long as conservatism has any place in UK politics, the UK should not be permitted to re-join. Conservatives will eventually just re-Brexit.
I see what you are saying, but I don't think you are completly right. Re-join can takes years and it will be under the EU rules, not UK, so no more special treatment like before. That alone is difficult to sell to UK, but I am not sure that if UK re-join people will vote again to exit, given that Brexit was sold with lies that was already exposed.
There is simply no place in a healthy, modern society for a conservative government. Let the UK rid themselves of their plague of conservatism first before being allowed to further harm the UE with this dangerous illness.
Disagree. A good government is a balance of progressivism and conservatism. Real life it is not black or white but a shade of grey (for the most part).
