I can't speak to the groups, whom I suspect are young, indoctrinated, mind-twisted people who were raised to reject traditions by using those traditions in their opposite ways.
Yahrzeit candles are memorial candles that are lit on the anniversary of the passing of a loved one. During life, we celebrate the birthday with candles, and after passing our loved one commemorate our lives with remembrance candles. I light yahrzeit candles on the anniversaries of the passing of my grandparents, and so on.
These abortion activists are desecrating the meaning of yahrzeit candles by using them to protest the ending of Roe v. Wade.

As explained by a friend who is a rabbi, the army in Israel is the Jewish Defense Force and their purpose is to defend Israel against all attackers and defend the state. When a child is in the womb, it is considered to be an attacker and should be defended by any means possible including abortion. I understand the concept but totally disagree with it. The rabbi stated that is why most Jews are pro-abortion. God says choose life. They got that one wrong - the pro-choice Jews.
