Theoretically and practically. We have evidence for this throughout the last 130 years.
As for advocating for “bloodshed,” revolution remains the sole path to end the bloodshed, especially of the genocidal US Empire.
As for LGBTQ rights, I am pansexual myself, and I can confirm that Socialist countries make faster progress on social issues. Cuba today has much better LGBTQ rights than anywhere else in the world, and countries like the PRC are gradually improving as well. Socialism, if anything, improves the rate of progress. Even the GDR began pushing for LGBTQ rights well before Western European countries and the US did.
Considering we are speaking about the US, those safety nets would come from the massive Imperialism the US commits constantly. Workers in the Global South would continue to slave away so workers in the US can live cushy lives.
In a Socialist system, we can end that, but under Capitalism there is no path to deliberately end the practice of Imperialism, as it forms the basis of US foreign policy, and why the US Empire has hundreds of millitary bases around the world.
