Definitely not anticolonial, they seem to be fueled by reactionary and frustrated former colonizers who long for the ghosts of the past.

There's potentially some use in pitting the national bourgeoisie against international bourgeois forces. Mostly I just think it's funny.

Leaving the European union is a good thing. The EU only weakens the people's power. The regional secession movements is a case by case analysis. Many are legitimate but many are just balkanization attempts by foreign powers.

Texas specifically would either change nothing in practice or weaken the empire, so it might be a good thing, although whatever government that forms thereafter would be incredibly unhinged even by right wing "standards".

I think that leaving the EU is a good thing, although I'm wary when it happens under capitalist states since then it happens because the ruling class thinks they can exploit the population better outside of the EU. This is what happened under Brexit.

Barely matters. The EU sucks but the UK gladly does anything shitty they would do as part of the EU by themselves anyway.

I'm in favour of any state that wants to leave the USA

Right decision, wrong motivation (and hilariously bad implementation).

Anything that weakens and diminishes the EU is a good thing. It is an unreformable, neoliberal, imperialist institution.

This goes double for the US. However i don't believe that any US state is actually going to secede. Their bourgeoisie all benefit too much from the federal government.

It was dumb reactionary bullshit that is continuously biting them in the ass.
