I am a member of PSL in a pre-branch, and COVID is an important issue we still discuss and are concerned about within the party. We have been discussing ways to enforce/encourage masks during our events as we want to protect people, especially the disabled and immuno-compromised. We recognize COVID as a form of genocide.
I do agree it is something we should speak about soon, especially for our campaign. Note that among the various issues for this presidential election, most people are concerned about the economy, more than anything else by a large margin.
One of the issues of enforcing strict mask mandates during our events is that we don't want to cut off some people that would be turned away from this but would have been open to learning about our program and eventually become more radicalized and educated. We have considered mandating masks, but by encouraging people to wear a mask during our events and making it a cultural expectation so that people who would not wear a mask feel uncomfortable not doing so. I am of the opinion we should be strict with it regardless because I want the disabled people to feel as safe as possible.
All in all, the issue is still on PSL's radar, but I would like to see an updated analysis of it, too. And yes, please join. Having more people join to bring these issues to the party is what we are looking for. If you can't join due to time restrictions, at least find a local branch within your area and let them know what issues are important to you. We need to know what matters to the masses so we can collect and analyze the data in order to make decisions based on the people's needs.
