I agree about gun zealotry, but if those are your two issues:
Biden has said he does not want to restrict most guns, but he does want to protect children.
Trump instituted gun control measures over his administration, and as with everything else has said he supports gun control and says he doesn’t support gun control depending on which crowd he’s talking to.
I guess you can consider that a wash.
But racial Justice? Clearly Biden all the way.
On those two points, biden’s clearly ahead.
If that guy is still undecided, then he cares significantly more about guns than he cares about racial justice or national leadership.
