Labeling pro/anti Q is how a lot of valuable intel gets missed. Like you indicated, intel is intel, one leads to the other, no matter what one's feeling is on the sender.
True intel or truth seekers put those labels aside and go after the information, scoop it up and verify.
Situations change and some of those who sided with one faction or another will start reaching out by dropping intel they wouldn't have dropped in the past and that intel can be missed merely because the position one has taken on their foe. Be aware, but always keep an open mind.
