WebYes, halogens are EWGs. Their inductive effect removes electrons from the ring, so they are deactivators. But their resonance effect puts more electron density on the ortho and para positions than on the meta positions. The deactivated ring still has more electron density at the ortho/para positions, so that's where an electrophile will attack.
