Is texting thx rude?

I'm curious to know, is it considered rude to text 'thx' as a shorthand for 'thank you'? In today's fast-paced digital world, abbreviations and shortcuts have become increasingly common in communication. However, some argue that using 'thx' instead of the full phrase can come across as dismissive or lacking in gratitude. What are your thoughts on this matter? Do you believe that texting 'thx' is an acceptable form of expression, or does it potentially undermine the sincerity of one's appreciation?
