Your point is "I don't do racist things, therefore there isn't a problem", which is just not true - there are still huge problems for tons of people with racism, sexism and other bigotry, and just because you don't see it or notice it doesn't make it not a problem. You got annoyed? I'm sure some non-racists were annoyed when all anyone could talk about was how bad slavery was. If you don't care about the issue, feel free to ignore it - but saying that people are imposing on you by caring is just unreasonable.
Being an island, Ireland was quite cut off genetically from the world for quite a long time, allowing a distinct ethnicity to develop. And as you may be aware, "race" isn't a real scientifically valid concept, but the word is used colloquially to refer to ethnicity, which is a scientifically valid concept that can be measured using genetics.
I already treat women as equal (actually more), same goes to my LBGT friends and colleagues, and same for all non-white people. But constant presence in media is making these topics so annoying to me, I wish more focus was dedicated to healthy lifestyle for example (probably being selfish here but that's my view, and view of people close to me too).
Things like company-wide emails encouraging us to go to gay prides over weekend "where you can finally participate and show your hetero support" - god damn I work for banking corp with 130k employees. If I wanted to go there, I would be already going for last 10+ years. I show support to the cause by treating them as equal, because THEY ARE EQUAL, not treating them like disabled kids. Keep work emails about work, and let me do my own stuff in my own time.
