One does not have to love a parent. But one should show respect for them as one who gave birth to you and show appreciation for them as our elders.
We have lost sight of that in the West but in non-Western cultures like the Chinese/East Asian Confucian culture, honoring parents and the elders is considered a duty that transcends everything else.
Young people must defer to those older than them because older people have experience and wisdom far beyond their years.
There is much profitable to be learned from one’s ancestors and those who do not esteem them will not see their posterity acknowledge them.
Tradition is an unbroken chain transmitted through the generations and is the cornerstone of conservative thought.
Sadly now we in the west is paying dearly for honoring those who are our elders or those in authority.
