Did a Marine named John Kevin Wood just sue the La Plata High School in Maryland because it forced his daughter to study Islam? No, that's not true: the lawsuit is real but it happened in 2016 and the suit was dismissed by the court.
The story reappeared in an article published by AWM on August 22, 2018 titled "Marine Is Suing School After Finding Out They Forced Child To Study Islam. Do You Support Him?" (archived here) which opened:
The separate of church and state dictates the religious affiliations should not be present in the public sector. The reason the Founding Fathers made this decree was because they wanted all people to have equal opportunity. If the state favored one religion over another, then people of the minority religion would become subject to discrimination.
Now a former Marine and his wife are fighting back after they believe a Maryland public school engaged in unconstitutional teachings.
They believe the La Plata High School was forcing their students to learn and do assignments about Islam.
Looking at the summary appearing on social media it is clear this is just an attempt to stir up emotions in order to get people to share and click without thinking:

The separate of church and state dictates the religious affiliations should not be present in the public sector.
In reality the lawsuit ("WOOD v. BOARD OF EDUCATION OF CHARLES COUNTY") already happened in 2016, the full decision can be read here. The conclusion at the end reads:
For the foregoing reasons, the Court will deny Plaintiffs' Motion for a Preliminary Injunction, ECF No. 17, and grant in part, and deny in part, Defendants' Motion to Dismiss, ECF No. 28. A separate Order follows.
