These are a few of my least fav'rite things... and why.

1. Parents who wear their children like jewelry or cosmetics. Having tutored hundreds of private students, I have witnessed too many children who have merely wanted to have a quality moment with mom or dad, or both, instead of being shuttled between soccer, piano lessons, baseball, hockey, etc., and who, in an attempt to gain their parents' attention, act out in a lesson because they don't know any other way to get their message across. They act out in the presence of another adult who might - just might - decode the behaviour and invite the parents to a consultation to figure things out.
2. Single people who fear and loathe commitment. As a contented single person, graced by God with peace of heart and mind with regards to a social life, and who hasn't been lonely for decades, and who enjoys sharing conversations and meals with others, it is always surprising to meet single people talking down relationships. Surprising, because their cheering of singleness sounds more like a complaint against relationships than a celebration of their own state in life. Sure, there are often reasons for the complaints and fear. However, how long should the complaining last? Resentment is an acid that corrodes the soul, erodes the capacity to forgive, and makes gratitude a distant afterthought.
3. Anyone - the ideologue, the degenerate, the academic - who exploits children as farmable commodities. Attempts to promote policies (i.e., social engineering) that rob children of innocence are detestable. St. Matthew 18:6
4. Identity politics. Character, yes. Identity? In this day and age?! When people barely recognize themselves in a mirror from day to day, does it make any sense at all to worship ourselves and by doing so marginalize entire groups of people solely because of an all-consuming preoccupation with superficial externals? This person of colour, yours truly, has no intention of buying into stereotyping, affirmative action (which has failed miserably) and other political acts of condescension. Let's bring the conversation around to what really matters: the content of one's character.
5. Public school officials who attempt to usurp the role (and authority) of parents. For all the education power available, the squeaky-wheeling few are drowning out the dedicated commonsensical underpaid wonderworkers who treasure the innocence of children and who actually teach core curriculum with zeal for literacy to enable young people to communicate effectively and to contribute to society as intelligent, informed and rational citizens.
6. Virtue signaling. The new self righteousness. Hypocrisy on steroids. Tell the "signalers" to put their money and time where there mouths are. Ask them to actually get their hands "dirty" serving those most in need instead of throwing money at institutions and programs that waste between 35% to 70% on administrative costs with relatively little support actually reaching people in need.
7. Politicians who claim to be devout Catholics but talk and act like infidels. Enough said.
8. Progressivism, a.k.a., left wing fascism. Enough said.
9. Protesters who destroy works of art to draw attention a cause. Beauty suffers at the hands of false prophets (iconoclastic ne'er-do-wells).
10. Anyone - the manager, the administrator - who enables bad behaviour or who protects bullies by taking sides with manipulators, narcissists, liars, cheats, and the entitled.
11. Incivility. Passive aggressive behaviour, for example, is far too often the habitual behaviour of people who fear having their ideas challenged. Feeling threatened, they gossip and foment dissent while avoiding the adult responsibility to engage in direct and meaningful conversation. They engage in a litany of microaggresive behaviours that destroy goodwill, collegiality and undermine confidence, all in aid of preserving some veneer of personal power and control.
12. Preferential hiring. A.k.a., racism, unjust bias. Affirmative action and EDI (equity, diversity and inclusivity) policies that reject better qualified workers merely replace one form of injustice with another. Affirmative action hasn't worked. The few benefit while most remain trapped in poverty. I was taught by my parents - a black and native Canadian father and British white mother - that quality of character, skill and achievement are the basis of merit, not skin colour nor any other external attribute (See Point #4).
