This might be futile, but here goes. The fundamental difference between the ideologies is that socialism works in a democracy where opportunities are made available for all to achieve their maximum potential, which is totally contrary to Marxism. Therefore, you can’t be a Marxist & a socialist.

"...and marxism there's no opportunities for all" wtf is this! again there's no evidence you provided. i don't care for your understanding, it's not facts this's just your opinion
