You have a point. Red dwarf stars are not the best candidates for stable, habitable planets because they tend to also be flare stars. And the smaller the star, the closer the habitable zone is to the star, making flares even more dangerous. But at the same time, the larger the star, the more difficult it becomes to find planets around them using the standard Doppler method. But leaving that aside and more to the point, finding a planet in a habitable zone with an atmosphere, and especially one with water vapor, would be a tremendous discovery, making extraterrestrial life much more probable. And an atmosphere containing oxygen would be an almost certain indication of life beyond Earth.
