For the person who experiences troubles it won’t matter that one other, 10 others, 100 others, 1000 others, or 10,000 others have the same or similar difficulties.
As another poster mentions, bulletins and websites can give a clue. If the bulletin is full of prayers to “Mother God”, there is no mention of adoration, Divine Mercy, links to the Vatican Web site or EWTN but links to “Busted Halo”, “Father James Martin”, “Unity”, “Womynpriests”, those are ‘red flags’.
Yes, "Busted Halo’ can have decent articles. Yes, Father James Martin is more than his LBTQ agenda. Yes, even links to protestant groups (though not the last!) can be judiciously used. But on the whole absent the OTHER links, they are problematic.
