Celtic was established to raise money for the poor Irish immigrants in Glasgow. They were fleeing the genocide enabled by Westminster during the potato famine. (From which the Scottish Highlands population never recovered from either - leading to the long-term decline of the shared Gaelic culture.)
What are you on about? Many of the Irish fleeing colonialism ended up in Glasgow so we end up with the situation described in the OP. Are their descendants not allowed to speak up about colonialism or are they not Scottish?
The elites orchestrated the union, the common people overwhelmingly opposed it, resisting English domination through events like the Jacobite uprisings and suffering brutal consequences such as the Highland Clearances.
Also shared ancestry and continuous migration cycles dating back to the Bronze Age have resulted in a significant degree of genetic and cultural homogeneity between our populations.
Dropping rapidly, and using reasoning models can solve most of it today.
It’s what the thread is about how is it cherry picking?
But that aside, hundreds of years before the Ulster Plantations, the MacDonnell clan migrated to Antrim and eventually became its rulers. They were likely descended from the Gaelic Scotti, the very people who migrated from Ireland to settle Scotland. So it all seems a bit arbitrary when you neglect the nuances.
Just as you can reference the Black and Tans’ Scottish unit, you can also point to the Galloglass warriors, who were Scots fighting alongside the Irish long before Protestant settlers arrived. Scotland isn’t just the Lowland Presbyterians, its history is deeply intertwined with Gaelic Ireland. They were basically part of the same Gaelic civilisation for most of their history until the 17th century when their (ruling) paths diverged due to English and Presbyterian influence.
