People are often adamant about their opinion, and believe that if people do not agree with them its because they are wrong. In the video below the Sephardic leader of his time, Rabbi Ovadia Yosef, tells how as a kid it was a mistake to give a quip statement chastising a person for driving on Shabbat. By chastising the person he is more likely to alienate the person than convince him not to drive on Shabbat. This is one reason why you Don't Demean The Opinion Of Opposing Counsel.
Maimonides one of the greatest Jewish sages of all times had the same problem in his youth. In the book Maimonides Life and Thought, the author Moshe Halbertal points out that Maimonides would go to great length to criticizing those who disagreed with. Maimonides's attacks on those who disagreed with him were so harsh he would often bring them to tears to the delight of his admirers. However Moshe Halbertal seems to suggest that Maimonides later acknowledged this was a mistake and stopped the polemic attacks as he got older.
PRESIDENT DONALD TRUMP
Donald Trump probably launched more polemic attacks against his opponents in his presidential campaign than any other candidate in recent history. These attacks probably did not result in any significant number of Clinton or Biden voters switching their vote to him. Although Trump's admirers did delight in his attacks against his opponents like the admirers of Maimonides it caused great division. The problem with making these attacks is they will likely alienate the people being attacked, and possibly result in a counter attack. This is what happened during the 2016 and 2020 presidential elections, as they were some of the most heated elections in my lifetime. Many people believe the reason Trump lost in 2020 is because he alienated so many people that voters came out in mass to vote against him.
CONCLUSION
In conclusion attacks on your opponent should be avoided. They are not likely to result in persuading the other side to your position, and will often result in a counter attack on you.
