Gun restrictions always follow the same roadmap. Increased background checks, licensing requirements, banning "high capacity magazines" and "military style assault weapons" (i.e. semi-auto rifles), banning or severely restricting handgun ownership, limiting the number of guns a person can own, making guns only available for target shooting and hunting (and not for self-defence). This roadmap was followed over the past 60-70 years in the UK, Canada, Australia, New Zealand and various European counties (basically, every western country outside the U.S.) If you think that the same thing will not happen in the U.S. if the Democrats have their way, you are completely delusional.
If the Democrats are ever able to gain a majority in the Supreme Court, they will start by declaring that the Second Amendment is a collective right, rather than an individual right. From there on, they will follow the same roadmap as the other western countries.
