<p>Allah yes, YHWH, Siddartha, and Vishnu no. The latter three refer to a specific person/god by name. Shiva, Vishnu, and Ganesha all refer to a god in the Hindu faith, but the three could not be used interchangeably. They refer to a very specific deity. </p>
<p>Meanwhile, YHWH is the proper noun name of god in the Jewish faith. The proper Hebrew word for god is elohim. YHWH is often confused for being the literal translation of god, but it is not. YHWH was often used to replace the word elohim to show that their god was the mightiest of all gods, and held dominion over all others.</p>
<p>EDIT LINE--------
r0kAng3l: Believing in a deity is in and of itself religious. You can’t tell an atheist to use god to signify the deity that they believe in.</p>
