A problem with top Dems being generally hostile to outside activism of most kinds is that it leaves the people who care without much to do. No one in power wants to admit "making life uncomfortable (within reasonable legal and polite limits) for elected Reps" has any impact on them, but of course it does.
That leaves writing checks, voting, and at election time volunteering with limited resources as millions go into the pockets of campaign consultants/ad companies.
