sikhs catch bullets when whitey gets violently Islamophobic, as far as the community goes I've only ever heard of solidarity.

Afaik it would be very incompatible. I don't know much about Sikhism but a quick glance brings the following:

There is only one God, and It is called the truth, It exists in all creation, and It has no fear, It does not hate, and It is timeless, universal and self-existent! You will come to know it through the grace of the Guru.

•  Sri Guru Granth Sahib

Sikh's believe that we should acknowledge one creator, and are against worshiping demi-gods or idols. "God" in Sikhism is regarded as an all-pervading spirit without gender or form, who is approached through dedicated meditation.

Sikhism believes that it is immoral to show distinction or rank because of race, class, or gender. Universality and equality are among the most important pillars of the Sikh faith. This is also known as https://en.wikipedia.org/wiki/Sarbat_da_bhala

Live by the three primary principles. Be always absorbed in meditation and prayer. Make an honest income by honorable methods. Share earnings and selflessly serve others.

Avoid the Five Sins of Ego. These are Pride. Lust. Greed. Anger. Attachment.

Become Baptized.

Keep the honor code. They are encouraged to forsake worldly worries, to abide by the guru's teachings and practice daily worship.

Wear the Sikh undergarment for modesty and health. Wear a wooden comb in the turban to keep hair clean and untangled. Wear a steel wristlet as a sign of faith. Wear hair uncut, to honor the creator’s intention. Wear a small sword symbolic of defending the religious rights of all faiths

Follow the Four Commandments. Do not dishonor the creator's intention by cutting the hair. Do not harm the body with tobacco or other intoxicants. Do not eat sacrificial meat. Do not commit adultery.

Recite the 5 daily prayers. There is a list of specific prayers you must recite each day.

Take part in fellowship. This could be many things, like cooking with someone, praying with someone, working at a temple, serving someone.

Sikhs are expected to embody the qualities of a Sant Sipahi or "saint-soldier", showing no fear on the battlefield and treating defeated enemies humanely. The Bhagat further defines the qualities of a sant sipahi as one who is "truly brave...who fights for the deprived"

Obviously religious people do deeply unserious things in the name of religion all the time regardless of the actual teachings of the religion, though. The base for Sikhism seems to be very accepting of other religions and is very obviously heavily influenced by Buddhism, Hinduism (particularly Bhakti), and Islam (particularly Sufi Islam). It has a strong undertone of demanding adherents be militant about equity. Bahaism is also very influenced by Sikhism, imo.
