I have studied and found Allah and His Qur'an is sufficient for me.
Shirk is only for the blind of reason and I do not know why I am quoting the Qur'an but here goes:
2:170 When it is said to them, "Follow what God has revealed", they say, "Nay! We will follow the ways of our ancestors.” "What! Even
though their ancestors (and the ancient Imams) were lacking in understanding and were not rightly guided?”
[5:104, 10:78, 11:62, 11:87, 21:53, 34:43, 38:7, 43:23. Hudan and derivatives = Prominent = Bright = Lighted = Clearly visible = Leading =
Guidance = Lighthouse = A well-lit road = A landmark of identification in the desert or sea]
2:171 The likeness of such blind followers is that (of a herd of sheep) which hear the shepherd’s call, but hear in it nothing more than a sound
and a shout. Deaf, dumb, blind, for they do not use their reason. [This is subhuman level of existence 7:179. ‘Unq = Shepherd’s call.
Shepherd here pertains to religious leaders who have learned some meaningless words or tenets, and a herd of sheep is the masses that
blindly follow them. Kufr embraces blind following in addition to denying, opposing, or concealing the truth. Perceptual senses alone cannot
distinguish human beings from the rest of the Animal Kingdom. It is the intellectual analysis that sets them apart]
