Take for example this question. Is religious discrimination legal in the USA. Numerous attempts to remove the offensive image were made, with the attempt to remove the offensive material and soapboxing. You can view the differences by looking at the revisions, with the side-by-side link
-After years and years and changes in minds and behaviors by education and communication, it seems terribly ugly and unbelievable - This statement doesn't appear to have any bearing on the question, and could only be used to influence and prejudge the answers.
-A link and quote to the news article bringing context to the sign was removed - Even with the original post unchanged, but only addition information to bring context to the sign (instead of trying to influence people to believe the sign was just discriminator because someone hated someone else.
Reports from Houston about signs in front of a parking lot have some people upset.
The Westview Shopping Center is across the street from the El Farouq Mosque in a Houston neighborhood. Some worshippers have been known to park in the shopping center's lot while attending services at the mosque, but it seems like the shopping center could've handled the situation a little more delicately. Several "No Muslim Parking" signs were posted on Westview's property, leaving worshippers feeling unnerved and upset.
-Attempts to generalize the question were removed - Removing the picture, and inserting a generalized question so as not to offend a particular group were ignored, (I.e. "Are [NO ' signs legal in public in the USA?")
-Even including all the OPs original question, but hiding the offensive image in a spoiler block were rejected.
This appear to me to be soapboxing. The OP hasn't provided justification for why the proposed edits diminish their question in any way.
