It relates to the fact that in some cultural-liberal circles, disruptive and disorderly protest is cool as long as it offends some groups (here, supporters of the Russian state and the Orthodox church), and not others (women who want an abortion). The concerns here, I think, have less to do with how inherently disorderly, tasteless or irritating the protests are, and more to do with people being really, really invested in being able to have guilt-free and shame-free abortions.
