I'm not familiar with the guy but I just want to suggest we be careful with this sort of thinking. It's one thing if he's just being very careful with how he talks about more provocative aspects of socialism, but far too many "palatable" socialists are actually just socdems. Bernie is a great example of someone who has "a knack for presenting socialism in a way that’s palatable to baby leftists/recently ex-liberals", because he literally isn't presenting socialism. It's not even 9 here so I can't think of any others but I know there are plenty... This muddying of the waters, imo, does us no favours.
"The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win.
