No one is claiming Freemason’s should be killed, persecuted, hated, or treated poorly. I don’t think anyone would claim that Freemason’s do only evil. They are simply stating Church teachings on being a Catholic and a Freemason.

Practicing Catholics cannot and maynot be Masons.

“The Catholic Church and Freemasonry have been at odds for centuries. Eight popes have condemned it, as well as have the majority of Christian denominations. Christianity and Freemasonry hold contrary beliefs. Catholics are forbidden to join the Lodge in the strongest of terms. The Church’s position is expressed in its “Declaration on Masonic Associations.” It states in part: “Therefore the Church’s negative judgment in regard to Masonic associations remains unchanged, since their principles have always been considered irreconcilable with the doctrine of the Church, and therefore membership in them remains forbidden. The faithful who enroll in Masonic associations are in a state of grave sin and may not receive Holy Communion.”
Here is an article f by CAF Founder Karl Keating on the topic

“What is the Catholic Church’s official position on Freemasonry? Are Catholics free to become Freemasons?
Freemasonry is incompatible with the Catholic faith. Freemasonry teaches a naturalistic religion that espouses indifferentism, the position that a person can be equally pleasing to God while remaining in any religion.
Masonry is a parallel religion to Christianity. The states, “Freemasonry displays all the elements of religion, and as such it becomes a rival to the religion of the Gospel. It includes temples and altars, prayers, a moral code, worship, vestments, feast days, the promise of reward and punishment in the afterlife, a hierarchy, and initiative and burial rites” (vol. 6, p. 137).
Masonry is also a secret society. Its initiates subscribe to secret blood oaths that are contrary to Christian morals. The prospective Mason swears that if he ever reveals the secrets of Masonry—secrets which are trivial and already well-known—he wills to be subject to self-mutilation or to gruesome execution. (Most Masons, admittedly, never would dream of carrying out these punishments on themselves or on an errant member)”
