I find it extremely ironic that you worry about scaring people off with practical details, but see no conflict in promoting a party which liberally uses poisoned leftist language. McCarthyism happened, the Cold War happened. Accurate terminology has been turned into boogeyman words.
The average American hears "socialism", and they think of gulags and breadlines and authoritarianism. I'm not saying that's an accurate conception, I'm just saying that's the consequence of a century of anti-left propaganda.
If you're worried about alienating people, start with your messaging. I fully believe that a socialist party will be substantially more successful if they embrace patriotic, market based, Christian language.
It's not socialism in the workplace, it's making every worker a stakeholder. It's not UBI, it's an investment in Americans. We're not sissy bleeding heart libcucks obsessed with handouts, we're spreading Jesus' message of feeding the hungry, healing the sick, and embracing immigrants as we were immigrants in Egypt.
If you care about the persuasive content of the message, then care about it. Don't clutch your pearls when people want their plans to be actual plans because that might scare people off, then push a party using poisoned language.
I don't oppose the stated goals of the PSL, but you have to realize that, in America at least, socialist vocabulary is more divisive and alienating than sober, pragmatic tactics.
