No, intolerance is a refusal to tolerate something. It is not the same as disapproving of something. For instance, my vegetarian boyfriend disapproves of people eating meat, but he tolerates people who do, including me. If he refused to keep anyone in his life who ate meat, that would make him personally intolerant of meat-eaters. If he argued in favor of commiting violence against meat-eaters to try to rid the world of such vermin, that would make him politically intolerant of meat-eaters. It is that last sort of intolerance that Popper claims we shouldn't tolerate, and even then he adds a bunch of caveats limiting when it would be acceptable to suppress such speech.
