Democratic Socialism is nothing but a rebrand of Social Democracy. There are two actual traditions in socialist parties. They are either revolutionary or they are reformists. Either they accept the capitalism superstructure (the state) needs to be overthrown, or they want to work through the superstructure to achieve socialism. There’s no middle ground as those two are two contradictory views on socialism.

Note that revolutionary parties are necessarily anti-reform, but reformists parties are usually anti-revolution. This is why every reformist party is doomed to fail. Capitalists will do everything they have in power to stop reformists from enacting their reforms. Since every reformist party rely too much on the liberal legality, they tend to be undermined by lawfare, smear campaigns, capitalists tanking the economy, military coups, etc. Reformists have the illusion that the whole legality of the liberal system will be enough to maintain them in power.

The main difference of revolutionary parties from reformists is that revolutionaries understand the need to fight through non legal means (not necessarily illegal, but outside of parliamentary legal framework). So, we plan strikes armed insurgency to counter a military coup, occupying factories and key strategic positions to maintain the economy circulating and so on.
