Perhaps, but it can definitely be said too much in one place.
It depends really whether changing people's minds and behaviour towards your cause is your aim, or whether something else is more important than that, like, idk, getting it off your chest, or virtue signalling, or shouting at people with different opinions and experiences, Not pointing any of these at you particularly, but at some posters on this thread.
Repeating it too much, too unpleasantly, too accusingly, or indeed with no solid answers to the resulting questions (e.g. where are these mythical innumerable kittens that I won't be told I can't take home because I have children/a catflap/no catflap/etc) has the opposite effect. Just RTFT if you don't believe me
Still waiting for the answer to the names and contact details of these mythical rescue organisations overun with kittens that can be allowed to have families with children, or in one pp's case by someone of an age that might potentially be able to conceive but is very clear she does not want to ever..
Not just from you, obviously, but if you know of any, that would be very much more persuasive.
