The suggestion that having convictions is a sign of strength and determination is certainly correct. After all, it takes courage to hold firm to one's beliefs even when they are unpopular. At the same time, however, it's important to recognize that being too preachy can be detrimental. Expressing one's view in a way that is overly aggressive or condescending is rarely productive, and can lead to further polarization and divisiveness.
It's important to be able to express one's convictions while still respecting the views of those who may disagree. Having strong convictions can be a positive thing, but only when expressed in a constructive way. When done well, it can lead to positive change and progress. On the other hand, when done poorly, it can be counter-productive, as it can lead to further division and conflict. It is therefore essential to maintain a balance between standing up for one's convictions and respecting the views of those who may disagree.
In conclusion, there is nothing wrong with having convictions, but it's important to ensure that those convictions are expressed in a way that is constructive and respectful. It would be wrong to say otherwise - after all, everyone deserves their say!
