If it were, given hundreds of millions of years of land-based life, we almost certainly wouldn't be here. Keep in mind that those CMEs that look so impressive in the videos produce a particle density at the Earth that represents a harder vacuum than can be achieved in a lab, and what's left is effectively blocked by our magnetic field and atmosphere. Other stars are more active, and ours may become so billions of years from now. But at the moment, we're safe (assuming we can recover from having our power grids or satellites knocked out... which are very possible consequences of flares that we know the Sun can produce).
