Devils advocate here...
Think back to our many conversations about campaign finance reform and repealing citizens united. Your position is that it's best for Dems to take the big money/super PAC money in order to complete on a level playing field, and then once they have a majority in both chambers/the White House work to repeal it.
What if social justice issues were similar? Would you be ok with Dems setting aside social justice issues during a general election in order to win their seat(s), and then once the Dems have the requisite majorities move issues like police brutality towards minorities, unequal pay for women/minorities, etc back to the forefront and work on those issues?
Would you support a strategy similar to what you propose for campaign finance reform for social justice issues as well?
