> Gaslighting is a form of personal attack that's designed to make someone doubt the validity of their own senses or personal experience.

Asking someone for a source (ie. "citation needed") isn't the same as 'gaslighting'.

There is no need to feel offended when someone asks for a source when you boldly claim something.

Using the website 'lmgtfy' and using this as source however is condescending. Say you are writing a paper. Would you then provide a Google search link as source? You wouldn't. That is why (indirect) Google links are not a source. Google is a tool to find a source.
