When MARS opposes the Libra SUN there’s a likelihood of argument and disagreement which could become heated. I would say to stand back if you don’t wish things to get contentious, but then, if you’re not going to make a stand now, under such critical transits, then you’re probably never likely to do very much at all.
If you’re not willing to be occasionally controversial; to make people think about their shit; worried that their ego is going to take a hit and as a result they’re not going to like you any more, then you should be primed for some offensiveness yourself. Truth is, you don’t want to think. You only come here to be right, unrivalled, entertained or flattered.
