It's simply a resolution from a neighboring city which has no standing so the star isn't actually going anywhere and yes, the reasons they gave for the resolution were relating to Trump personally:
"On Monday night, the West Hollywood City Council voted unanimously in favour of a resolution to ask for the removal of Trump’s star, due to the president’s “disturbing treatment of women and other actions that do not meet the shared values of the City of West Hollywood, the region, state, and country.” It cited President Donald Trump’s lewd comments on the Access Hollywood tape, his policy of separating families at the border, and his denial of Russian interference in the 2016 election."
