The difference between traditional union organizing and the social justice crusaders here is that the unions were fighting management to improve the material well being of the workers. They wanted more sick leave, higher wages, etc.
The present-day crusaders are attacking their fellow employees (who disagree with them) as well as customers (trying to get customers who disagree with them dropped). They are most certainly not fighting management. Management gets involved in those cases where it tries to stop one of the crusading employees from harassing another employee or customer, at which point there are demonstrations to try to get the enemy coworker or employee dropped.
That is why this is not at all like the unionization efforts of the past.

"Crusaders" already belies where you stand on this, but to be clear: historical labor movements absolutely included hostility against coworkers. The coworker who didn't join you on the picket line was called a scab.
Besides, US labor law places broad restrictions on the ability of labor organizations to call for boycotts (i.e., retaliating against customers). If you take your time to read about this history of workers' rights in the US, you'll find deeper parallels to the current day than you're probably currently inclined to believe.
