I'm going to break this down because like everyone else here you don't have the background.

1.)this guy posts about Boris Johnson and moderates a British tabloid sub.fair to say he is currently living in the UK and supports to some extent the armies actions on that day.(regardless of his age)

2.)In '72 Bogside was segregated.hard to believe right?the guy who shit called knew this.

3.)Fair assumption that a British child wasn't out for a stroll in 1972 in Northern Ireland during a civil rights movement.IF he was there he was at least 18,plus 44 makes makes 62+ years of age.

4.)If he was there at that time,and remember it was a VERY different time,as a Brittish loyalist the only plausible way he would be on that street on that day as he claimed would be if he was either British military or BBC news crew.N.I. can be forgiven for not realizing it would cause confusion other people not knowing that area was so locked down in those days.

5.)so what we have is a British ex army or BBC newscaster who spends gos day on reddit posting about boris johnson,pokemon and asmr or we have a former Irish resident of Bogside that wants to defend the British troops that killed his unarmed neighbour or possibly we have a jeekoff kid with some riggt wing views that thinks its fun to shitpost about a bunch of teenagers that got chased down alleys and shot in the back, magicalky without the might of the British army incapable of finding a gun, spent round or even a shell casing that wasn't one of theirs?

BTW what this kid is talking about is an event that sparked 40 years of bombings and assasinations on both sides and didn't end untill thousands of innocent people on both sides were dead from collateral damage,it's a touchy fucking subject to say the least.
