Mercury in Cancer opposes Pluto Rx at 11 degrees Capricorn today (July 21st) although this aspect is not exact until tomorrow.
You may feel this if you have natal or progressed planets/angles/Nodes from 10-12 degrees of the Cardinal signs. Mercury (as the faster moving planet) is the trigger. Words/thoughts that come from an emotional (Cancer) place can set off compulsive power struggles (Pluto), or the irrational sense that someone is out to get you. This is assertive energy, but it's difficult to control. If you offend someone, your words probably pushed a button that's buried deep within.
Pluto also represents the Shadow (the ugly/underdeveloped/fearful/destructive side that we all have), and an opposition is projection. Chances are, any hostility that's sensed in external words is being projected. If you think they're saying something manipulative, check your own issues first. If they overreact to your words, they could be projecting on to you. It works both ways, so thankfully this is a very brief influence.
Overall, don't take anyone's words to heart today or tomorrow, unless you feel like taking an unblinking look at your Shadow. There's a time and a place for that.
