Radio Waves & DRAGN

I turned to the History channel and learned about The Universe:

~ pulsar radio waves and its killer radiation
~ neutron stars
~ Earth's pending collision with Andromeda
~ Something can be so black that it's bright
~ Black holes inside Quasars are called monsters
~ DRAGN is Double Radio Active Galactic Nuclea
~ Radio galaxies = blazares

There are three different names for the same kind of star (pulsar, quasar, blazar) but they are actually the same. They look different based on the viewing angle or line of sight.

So, does this not suggest that we can communicate via radio waves with other star intelligences?
