Annoying siblings

So I have brother he really annoying and really like to expose someone privacy, he like to see my chat with other ppl, and he ever read my chat in group ( Line BL group) and he scold me for liking that, he says it was a sin for supporting lgbtq+
And he reallllllly hate banana fish when it first come out and told me how really bad that anime was, and I download the anime and it was really good, then he found out that I watch it ,and told my mother that I watch "gay anime", my mother just silent, and I was beside him, he really proud of himself, I really want to choke him with a dildo, and every time he heard lgbtq in TV he want to know my opinion abt them, press f to choke him :)
