Fascism is born from economic issues and tention usually created by rich people to move the blame. We have a labour party in place in the UK, Elon Musk has already involved himself in our politics. Reform uk is poling 25% and labour 26%. labour hasn’t even been in for half a year.
Fascism is battled in the streets and unions, historically this is what has happened.
Fascism can be seen as the endpoint of capitalism, when a system predicated on infinite growth hits the ceiling. While yes vote in your interest I wouldn’t depend on politicians to fix the systemic issue that is capitalism.
Edit for clarification: Reform UK are a nationalist party. Labour were a socialist party for workers, now they are liberals willing to sell whatever isn’t strapped down.
None of this changes the fact that by not voting against the fascists, you’re doing nothing to prevent them from taking control of the government.
