By acting as an apologist for paypal.
This is not hard to understand.
In a one sentence post you invented a scenario to attempt to excuse or explain their actions while at the same time bringing up the dreaded, super-scary "right wing media" to shift discussion away from the clearly reprehensible actions of PayPal.
apologist? GTFO here, I'm clearly chastising righties for trying to politicize the issue (you clearly formulated in your head some conspiracy that it's to influence the election already, if we're talking invented scenarios). Of course the focus here is corporate greed on some faux-veneer of social justice, not whatever Alex Jones or Breitbart is running w/today.
I'd be just as outraged if the opinion of the day was to penalize immigrant remittances and Paypal decided to pull a similar stunt on alt-right support.
