Not invented here : institutional resistance to practical solutions

The theoretical advantage of single-issue pressure groups is that they can form broad coalitions, gathering people from across the political spectrum who need not agree on anything other than the group's single issue. For example, Women Against State Pension Inequality (WASPI) is a group that campaigns for financial compensation for women affected by the increase in the state pension age. That is all they do. WASPI do not express a view on whether or not Britain should rejoin the EU, abolish the monarchy, convert the House of Lords into an elected upper chamber, or replace the First Past The Post electoral system with Proportional Representation. With that strategy, they have managed to attract support from many different corners of the political spectrum without attaching themselves to any of those. Curiously, though, many high-profile single-issue pressure groups are not like that at all. Black Lives Matter (BLM), Extinction Rebellion (XR), Just Stop Oil (JSO), Mermaids, the Stop the War Coalition (StWC) and the Palestine Solidarity Campaign (PSC) are very much not cross-ideological broadchurch coalitions. They are remarkably politically homogenous, including on issues that have nothing to do with their stated cause. They draw almost all of their support from one specific corner of the political spectrum. (...)
