How would anyone have knowledge of "many communities"? Do you spend time and resources in the many to understand and observe? It is nothing but a blanket statement that has no merit. Where do you draw the line from many communities to not all? What is the percentage? Many politicians are; lying, hypocritical, self-serving egotistical dishonest whore politicians. Are all?? Blanket statements zero value.
I can see how you might not understand the context of "many communities." Words like "many," "some," "few," "a lot," and "most" are not precise statements. They are meant to be qualifying generalities that have no amount or number intended. People use them when there is no way that they can discover or find a more accurate term to use instead. No percentage or number is intended in such cases (if a percentage or number could be found somewhere - well, that is something that the writer didn't know about, was too lazy to look up, or is out of reach in terms of researchable data). There is no line that can be drawn between the "many" and the "none" or the "all of them." It is a generalized term to use so that the explanation of the issue can continue without becoming too wordy. Using the word "many" does imply, however, that the number of whatever is more than "a couple," "a few," or "some." It also implies that the number is less than "most," "all," or "almost all." It is a convenient "middling" term, and is usually pretty safe to use. It is to be understood that it is not an accurate term. If the reader wants more information, then they can do the research and perhaps find a more accurate number.
In terms of "many communities," the US is so large that "many communities" can be safely used to describe almost any issue - there are so many communities. If the issue concerns something essentially rare, then the term should be obviously inaccurate (for instance, "communities living near a copper mine" - everyone knows there aren't many copper mines). I believe this issue concerned churches and perhaps other religious organizations helping the needy. A fine and noble cause, but there is so little news or information on this happening, that the easy-to-think impression is that there are not many/enough of them. For one thing, helping the needy is very expensive, and most organizations that do help either can only afford to do it sporadically, or else they receive funding from somewhere. Churches themselves are not known to have great resources. Labor can help, but there usually are material costs of some kind involved.
In terms of your statement on politicians - saying "all" would be a blanket statement; saying "many" is not. The term "blanket statement" means complete coverage (like a blanket), so a qualifying term would not be a "blanket statement." Perhaps you could consider "many" to be a questionably inaccurate statement, but to say so would require a reasoned explanation.
