May’s government is weak, shambolic and crisis-ridden. The last thing it wants or needs is mass protests on the streets. As soon as Trump touches down on British soil, this is what will happen. That is their choice. The biggest carnival against hatred this country has ever seen awaits. From LGBT rights to women’s rights, from workers’ rights to anti-racism, we already know that protest works. Both May and Trump deserve to learn this instructive lesson.
